Dicrossus sp. Rio Negro

This is a fish that I got at the 1984 Detroit ACA Convention. I believe Dolores
Sherr (probably wrong spelling) had spawned them. Unfortunately they didn't
handle the 2 day trip back to Denver well and lost most of them. Consider them a
difficult species requiring extreme blackwater conditions for breeding. Wolfgang
Windisch wrote an excellent article on this fish, including natural history &
breeding, in: Windisch, W., 1992, Dicrossus sp. „Rio Negro, D.A.T.Z. 45(12):
767-770. ASG members can get a copy of this article + an English translation from
me.

Dicrossus sp. Rio Negro

Hi Mike

Thanks for the info, I set them up in the same manner as I had success with 
filamentosus and maculatus. They look real good for fresh imports and are 
eating well. I happened to be there when a local wholesaler was delivering 
them and took the whole bag & ordered all the rest he had to insure I would 
end up with some that would live expecting them to be delicate. How can I get 
a copy of the D.A.T.Z. article and translation? (I am an ASG member) I have 
the Romer book also but German is not my language (barely English). 

Thanks 

Tom Wojtech

WIDE span of behaviors across Dicrossus

Just a question/observation for those of you out there who've kept 
any of the various Dicrossus spp.

D. filamentosus: quite shy and retiring.

D. maculatus: less so.

D. sp. "Red-finned Rio Negro": almost aggressive!

I'm keeping seven adolescent (4M 3F) wild-caught D. sp. Rio Negro in 
a 58G with 8 Nannostomus espei, 6 sailfin tetras (Crenuchus 
spilurus), 6 Hyphessobrycon robertsi, 6 Mimagoniates microlepis, and 
a single flat flyer pleco (L235-ish).  I've got a friend who kept 
about 10 D. sp. Rio Negro along with C. spilurus, until he saw the 
Rio Negro attack a C spilurus and kill it.  This is someone who's 
kept and bred fish for many years, and I think the story is reliable.

My Rio Negro have never been that mean.  As a matter of fact, there's 
not even very much male-male strife.  However, they're far from shy: 
never do they run and hide, even when a net's in the tank.  They swim 
boldly up to anything in the tank to check it out.

Has anyone bred these fish?  My only reference is the Tetra Dwarf 
Cichlids book (Horst and Linke) and it mentions that they're the 
hardest to breed of the known Dicrossus spp.  I've got them in 
peat-filtered pH 6.5 water, and they're really coloring up nicely. 
Even some purple in the caudal fin.  Anyway, any tips or tricks would 
be appreciated.

Also, I've added some Marc Weiss Instant Amazon as directed on the 
bottle.  I have no idea if it does anything, but it hasn't hurt.
