> o.k. i want to be a nudibranch fan ....
 Well , get a chiller and keep your water around 65 degrees.
 Then get around 8 aggregating anemones from a warf from central
or northern california.  Then find some salmon gilled nudibranchs, 
ussually hiding around the rock - where it is wet but perhaps between
the low and high tide marker. (p.s. make sure you do this in some 
comercial area cause california has some major penalties for messing
up tidal pools).  the nudibranchs will feed on the anemones, feed the
anemones large brine - small shrimps - and they will be able to propogate
fast enough to maintain the nudibranch.  Nudibranchs are powerful predators,
i've seen large ones snuff big anemones (upto 3 inches wide) in a single
meal.  Seems like all the nudibranchs (temperate) i've seen feed on anomenes,
and its fairly easy to figure out what kind of anemones they like - the 
problem is maintain the supply :) 

I think it is fun to have nudibranchs long enough to prove to yourself that
you can maintain them for long periods, but i'm not sure they are worth the
effort/destruction after you have thrilled yourself that you maintained a
nudibranch (i.e. keep nudibranchs as stunts of being a masterful aquarist -
pat yourself on the back - then move back to something normal [ i have a 
guppy tank that i enjoy ... very much ] ) .

Any one thinking of raizing anemones, etc ... should buy "the temperate
reef aquarium" by david wrobel - get it by mail order from California
Reef Specialist (they have adds in FAMA).

and speaking of strange nudibranch dietary requirements, that reminds me
of a story....

A couple months ago i noticed that a recently purchased piece of rock
covered with encrusting coral polyps and "x-mas tree" worms was changing
-
the polyps were dying.  Every morning i would look in the tank, early, 
and it looked like some of the polyps were hanging out of their little 
holes.  Then later that day, the area was white and dead.  This went on
for about a week, and i lost about a quarter-sized area of polyps, when
one morning I SAW THE SPOT MOVE.  It was an _incredibly_ well-camoflaged
nudibranch, munching on coral polyps....

He's gone now (evicted), and the polyps grew back.
