dude, ive actually had a guy working at an LFS tell me i could keep a shark in a 20g long tank, thats how these guys work, they want to sell the stuff, so they will tell you anything in the world to sell things, and while the pygmy cherub angel is small, he's absolutely beautiful, and makes a great addition to any tank, and while i know u dont like the nemo fish, have u looked at all the different varieties there are of those guys? im goin with the b&w O. clowns because i dont like the look of the typical nemo's. if you want man, take a look at my future tank build in the fish only section, complete with diagrams of what im considering doing. and look at all the other builds, people on here have gotten really creative, and all of us will help you do whatevr it is you decide to do, thats what we are here for man
