There was a fish I saw at my LFS but I didn't see what the name of it was. It was a sort of powdery bluish color, rounded, small and stayed near the bottom of the tank, so I assume it was a bottom dwelling fish but it might also have just been stressed. Umm....I know this is not much to go on but I'm hoping people might have some ideas? I won't be back at that fish store for a while and I really wanted to know the name of the name so I could do a search on them and see if I could possibly keep some. TIA!

Powder blue immediately makes me think of dwarf gourami (they come in a powder blue color) but they're more of a top dwelling fish...
