hi all. i've had this fish since april 06. and i never really figured out what it is. figured i'd post it on here, and see what ppl think. he is ussualy purple with bars, but have seen him all blackish/brown dark. he is starting to grow a kok. and he is around 5". he also has a very nice blue color along his chest and gills.
ok at first look it appears to have convict in it.
but i think its possibly something more interesting. picked what appeared as a pair in a LFS, they didn't know what they were and sold the pair for $5. Lost female couple months ago. when i went on vacation.
sorry for darn water marks on glass, didn't notice them till after pics were taken. also that freaking alge just won't give up
only tank i got with this prob. (so far)
