At a lfs by me, they have a puffer, I couldnt tell you what kind, but its over a foot long, in a 20 gallon tank, the poor thing can hardly move. For about a week, they had a yellow tang in with it, and one other fish...in a 20. I went back a couple days ago to see if anybody died, and the yt and other was gone, but the puffer was suffering a bad case of ick. Its pretty sad, considering the rest of the store is really nice.
