Once when I was looking for a challenge, I tried to create all the fish on the poster. Some of the fish on the poster are hard to figure out. Some of them are real fish, and unfortunately we can't make those. The purple fish I think you're looking at is a real beta. Drats I know, 'cause that one's really pretty!
There is a purple leafish on that picture but I can't tell what it's fins are.
The one's I figured out are:
greenfin beta
pink fruitfish
silky shark
orange pygmy
snubbed snooper
twin-fin fatfish
finless grouper
oriental flashfish
golden spotanus
there is also:
something goldbulb
something quicksilver
great-sail something
and a few small fish that may be goldshark, fire-arrow, and comet

If one of you can come up with a larger poster that's clear enough to tell, I'd be grateful. Of perhaps one of you LDW people know what they are?
