I ordered 10 about 2 weeks ago. They sent 12 in case any were lost during
transit. They arrived Fed Ex 2 days after I placed the order. All 12
arrived safe and sound and are all doing wonderfully in the 140 gal
plant/discuss tank. The charge was $5 per fish (charged only for the 10)
plus shipping. I would recommend both the shop and the fish. They are

The two adult SAEs I have do the same thing every now and then. I think they
are of the same sex, because they have same body shape.
Here is Finland, where nearly everyone has SAE in their tanks, I have heard
that some of them get very plump when adult, and if a fish like that dies
and you cut it open, it is full of eggs. According to books it hasn't been
bred yet in captivity. Something is missing - bigger tank, more flow,
right temperature or pH?

the wholesale listing as small flying fox. After we discussed the
differences among the related species with this firm, the identity crisis
is no longer a problem. The true SAE are now regularly appearing in

We ordered 20 to be split up among us - when our order arrived, all 20 fish
had survived!! (I had ordered 10 previously from Albany and 2 were DOA and
another died a couple of days after receiving them). The fish that I took
(11) have all survived. They also gave us a great!! deal - they advertise

Neil and I had never seen any reports on breeding SAEs during the time
when that article was written and published. There had been rumours of
breeding, and some good reports on "breeding dance" without any egg
laying. Now they have been bred and this has been documented:
Doug Underwood has just managed to produce viable fry this summer, and
you can find his posting about it from the APD archives. So, it is
possible that your brand new SAEs will breed one day too!

Regarding the SAE's feeding behavior... the very first tank I put my SAEs in
four years ago was a 40 gallon tank with red algae. The six fish quickly
eliminated essentially all the algae, except for some long filaments that
were growing out from the holes of the submerged Eheim filter spray bar.
Even after a few months, this algae remained, but was the only visible red
algae in the tank. I replace the spray bar with another one and dropped the
red algae covered spray bar to the bottom of the tank, and in no time the
algae was gone.
This is another example of them not feeding near the surface. I had
attibuted it to the current, but its position may be the important variable.
I checked this morning, and I still have red algae on the active spray bar.
I did another switch, but this time moved the static bar to a position on
the front glass near the water surface. My eyes will be pealed.

Oh, yeah, fer sure.

It's made in two L shaped pieces for easy removal for maintenance. The

I did a little research on the genus Crossocheilus and here is
what I came up with. Let me first reiterate that cyprinids are not my
specialty. My area is Asian catfishes and my interest in Crossocheilus was
peaked when I found out that a Crossocheilus sp. (C. pseudobagroides) is a
mimic of the catfish Pelteobagrus ornatus. However, that is another
The two SAEs that I am keeping really do chow down on black hair
algae. I honestly do not know what all species of algae this includes
since my brain only has enough room for the scientific names of fishes and
plants and I never plan on taking up algae farming as a hobby (thanks to
Tyson Roberts included three spp. of Crossocheilus in his book
"The Freshwater Fishes of Western Borneo" (California Academy of Sciences,
1989 ISBN 0,940228,21,1). One of these sp. is undescribed. Looking at the
photo all three fishes look exactly like what we call the SAE in the
hobby. The key to the genus uses such distinctions as "rostral cap with
14-15 fimbriae" so you can see how useful this is to the hobbyist with a
live fish. All of the "usual" guides that we use to tell the SAE from its
look-a-likes (such as the stripe goes through the caudal fin and above the
black stripe there is no yellow stripe) are the same between these fish.
Tyson Roberts only noted one Crossocheilus sp. in his "Freshwater
Fishes of Java" (Leiden: Nationaal Natuurhistorisch Museum, 1993 ISBN
90-73239-17-6). The book only contains a water color painting of this fish
so it is not very useful. An interesting note is that Kottelat and Lim in
the "Freshwater Fishes of Sarawak and Brunei Darussalam" do not mention
any spp. of Crossocheilus. Inger and Kong also make no mention of
Crossocheilus spp in "The Freshwater Fishes of North Borneo". I do not
know if this means that the genus is restricted to Western Borneo. I have
no information on Crossocheilus on the main land (i.e. the SE Asian
Peninsula). Liisa mentioned that someone was doing an article on the genus
right now. Until they publish, there will be unanswered questions.
However, there may be some truth to the theory that atleast two spp. of
Crossocheilus are being imported. One that likes hair algae and one that

One explanation for this is that the SAEs are getting enough fish
food to curb their appetite for red algae. Many have noted and warned
that SAEs' red algae consumption rate goes down when there is an abundance
of fish food, which they prefer.

I have :-). When we first received some in our store, I ran a
little experiment: I isolated them all in one chamber of a system, and
began introducing red algae infested plants from other systems into the
chamber w/ the SAEs. I watched them as they began to swarm over the red
algae, greedily nibbling away. They virtually wiped out all the red algae
on those plastic plants, and on other plants I put in subsequently. While
they were eating red algae in one chamber, I took other infested plastic
plants from other systems, and put them in the same system as the SAEs,
but in a different chamber. The red algae remained on those plants, until
I moved said plants into the chamber with the SAEs. These SAEs were
relatively young, being about 1.5". During the couple of weeks I was
running this little experiment, I made sure to feed the SAEs very little
fish food. The SAE chamber is now being shared with some young
surinamensis (or proximus or ...?). Thanks to the gluttony of the little
surinamensoids, lots of food goes in there, and perhaps coincidentally,
the consumption rate of the red algae has slowed to just about 0.
Different size SAEs have been in there with the surinamensis, including
some the same size as the original batch, but none have shown that much
interest in the red algae.
The red algae was, btw, not what i would call young and fresh,
since it had been on the plastic plants for some time, and much of it was

In addition to the above piece of pontification :-), let me add

Here I go again with cucumber -- it's so easy to feed and really
inexpensive. It does not keep the SAEs from eating algae, but it does keep
them from nibbling at certain soft plants that they seem to enjoy when
cucumber is not offered. They seem to have a voracious appetite and will
eat anything that you feed your regular fish, but that is not enough for
them -- hence, the cucumber. Many fish seem to enjoy nibbling at this
vegetable and Altum Angels wait around for the softer seeds, so what can
hurt? Of course, Clown Loaches love cucumber and will stop punching holes
in Amazon leaves. I also noted that "That Fish Place" actually has a
cucumber feeder advertised.

I fallen a bit behind in the maintenance of my open top tank and have been
rewarded with the loveliest blooms on the Heteranthera zosterifolia that has
grown to the top. I'm thinking of letting it remain at the top for a while
so I can enjoy these dainty flowers. Does anyone know if allowing this bloom
to continue will lessen the vigor of these plants?
BTW: This is my first open top tank (a 125 gallon). About a week ago I
experienced the downside when I found my missing seventh SAE on the floor
behind the tank. Tonight, however, I discovered that I still have seven SAEs
(at least). Apparently, they spawned. It must have been some time ago
since the young SAE I saw was almost an inch long. Wish I had noticed; I'd
have put sponges over the filter intakes at least.
All of this is very exciting. This is the first tank I've set up since I
started following the APD (though I been amending the others right along).
I owe a bunch of thanks to all of you who share your information so
generously on the list and to those who have taken the time for
amplification and clarification in private email. I've never before
experienced anything close to the phenomenal plant growth taking place in
this tank. And I'm both surprised and delighted with the positive affect
this environment seems to have on all the fish. I could go on and on.

The following is reported by Harro Hieronimus of Germany in
"Aquatic Survival: Bulletin of the Aquatic Conservation Network, Volume 2,
Number 1 - March 1993" (http://www.holidayjunction.com/acn/as/v2no1.html).
"...Crossocheilus siamensis - This loachlike fish is also one of the
most well known aquarium fishes as it is known as a good algae
eater. Thousands (to be honest, it must be tens of thousands) of
these fish are imported by wholesalers every year and it is no
problem to get as many as you want. However, according to my
information this species is extinct in nature now as a result of
the same dam building which is responsible for the vanishing of B.
sidthimunki. The fish are bred in Thailand, also hormone induced.
Nothing is known about the breeding biology of these fish except
for some reports (which are very superficial) of aquarists who
I hope someone can comment, preferably to 'say it ain't so.'

Luckily this extinction thing isn't true, as far as I know. I have heard
about that dam too. Probably it had been built and it has affected many
fish populations, including SAE and Botia sidthimunki, but as both these
species live in much more than just one river or river system, they can't
be wiped out by just one dam. Some fish importers say that sidthimunkis
have been rather rare and expensive, but still available regularly and
there has been no change in the availability of SAEs.
If SAEs were bred in large quantities, there would probably be some change
in their quality, size or prize, but nothing like that has been seen.
About breeding SAEs:
go through the archives of this list and search for the breeding articles
by Doug Underwood and Shane Linder during summer and autumn 1996.

Zsolt Csillag was asking about SAEs and what they looked like. I believe
someone provided a pretty good site that describes SAEs fairly well.
However, I would like to add a few additional tidbits about them. I have had
SAEs for over two years now and while they do help in controlling algae,
they are not miracle workers. You will still have to do your part in
controlling algae (lights, nutrients, water changes, substrates, etc.,
Another fact about SAEs that I have learned the hard way relates to their
seemingly lack of tolerance of low oxygen levels. After losing several SAEs
following severe plant trimmings, I finally wised up and started allowing
for more surface agitation for at least 12 hours after any trimmings that
amounted to more than just removing a couple of leaves. I am not sure, but
it seems to me that plants don't produce as much oxygen after they have been
trimmed. I don't know if it is just the lost of plant surface because of the
trimming, or if the plants actually shut down after being trimmed. However,
I do know that oxygen levels decrease significantly afterwards and you have
to keep an eye on your SAEs becoming overly stressed. I have even had some
larger ones jump out of the tank in search for more oxygen. I might add that
I inject CO2 and I could decrease its output for 12 hours too, but surface
agitation is easier for me.
One other thing I have learned over the years is that there are usually two
SAE characteristics that you can depend on spotting with SAEs even when they
are under a lot of stress. Look for the lack of color in the fins. If you
see ANY color, it is almost a sure bet that they are NOT SAEs. Also, in most
cases, the dark lateral strip will go all the way to the end of the tail
(not just to the base of the tail). Sometimes, if they are completely
stressed out at the LFS, it might be hard to tell if the stripe is all the
way to the end, but give them a few minutes to calm down and you can usually
see it. If the strip is not completely to the end, they are NOT SAEs.
I have found that in your home aquariums, SAEs do school and Flying Foxes
don't. However, all of them will school when they are stressed out in the 10
gallon tank at the LFS. So I wouldn't rely on that trait when buying them
from a LFS.
For those of you who are lucky enough to have places to buy them, I hope
these few hints will help you find the right ones.

some high quality pictures of them. If you've seen any other "SAE
mistakables" (like Garra sp. or Epalzeorhynchus sp., please change the key!)
1A. Mouth is in the form of a clinging suckermouth
1B. Mouth is not in the form of a clinging suckermouth
2A. Horizontal stripe is well defined
2B. Horizontal stripe is irregular or "checkered"
Chinese Algae Eater, Gyrinocheilus aymonieri (Tirant, 1883)
3A. Dorsal fin has dark top, with white edging
Flying Fox, Epalzeorhynchus kalopterus (Bleeker, 1850)
3B. Dorsal fin does not have distinct dark top, with white edging
4A. Lower rays of dorsal fin are dark
"False siamensis," (Epalzeorhynchus sp. or Garra taeniata)
4B. Dorsal fin clear
Siamese Algae Eater, Crossocheilus siamensis (Smith, 1931)
Other Characteristics of above species:
Otocinclus sp.: Color above horizontal stripe is dark, and below is light.
Small. Often seen clinging to aquarium glass.
Chinese Algae Eater, Gyrinocheilus aymonieri: Color is a brownish-grey.
Large distinct scales.
Flying Fox, Epalzeorhynchus kalopterus: Boldly colored fish. Horizontal
stripe continues on into tail. Horizontal stripe edge smooth. Distinct
yellow stripe over dark horizontal stripe.
"False siamensis," (Epalzeorhynchus sp. or Garra taeniata): Horizontal
stripe does not continue on into tail. Horizontal stripe edge smooth.
(NOTE: Any personal observations of "False siamensis welcomed!)
Siamese Algae Eater, Crossocheilus siamensis: Horizontal stripe continues
into tail, but it is no as bold or thick through the tail as it is through
the rest of the body. Horizontal stripe edge somewhat grainy or "zig-zaggy".
Sometimes possesses lighter stripe over horizontal stripe. The light
stripes in the specimens I have observed were not so distinct as in the E.
kalopterus. Assumes peculiar resting position, raised off of the floor on
its dorsal and tail fins. Nose has a somewhat "rat-like" appearance.

Thomas Barr suggested among other things that I try SAEs to clean
my willow moss of BBA. My response was, "As for the willow moss,
I think that the SAEs would have trouble cleaning it without
tearing it apart." I tested his suggestion anyway, and it worked.
I cleaned the tank and removed all fish and snails. In five days
the four SAEs did a respectable job of eradicating most of the BBA.
They do not appear to have torn or shredded the willow moss.
Thanks for the advice.
I still waiting to hear from someone with BBA on a Schluerti sword.

Andrew, SAEs have a breeding season once a year in wild, and it seems
to be in spring or early summer. The youngsters are most often
caught on autumn, when they are 2-3 cm (about 1") long and then they
are most easily available at least here in Finland.

They are rather long-lived, and live easily 10 years or more. Your
fish didn't die of old age.

<< don't know why SAE's and Amano shrimps EVER got so popular w/ us plant

That last line is the important one. The SAEs are valuable because very
little else eats BBA. If you never had it, you wouldn't need them.
The effectiveness of these fish was recently demonstrated to me. To
fight a green water outbreak with daphnia, I suspended a breeders box wrapped
with a nylon stocking from the tank's center brace. This was the favorite
surface of my three young SAEs, they would constantly clean the outside
surface of it with their mouths. When the water was clear, about ten days
later, the outside of the nylon was clean while the inside had a uniform,
half-inch layer of black hair on it, thick enough to significantly restrict
current through the box. There was no other visible algae in the tank.
BTW, I had no trouble related to the use of nylon stocking in the
tank, but since another contributor had trouble with nylon poisoning, I would
make sure to use only stockings that had been washed several times in the
For what it is worth, the daphnia were very effective, but the box looks
silly. Since it is a recurring problem, I use a flocculant and a diatom
filter. If I had a sump, I could probably make a permanent refugium in there
for the daphnia, as mentioned somewhere in the KRIB.
I was going to ask what FFF was- just realized it is Florida Flag Fish.
