Omg. I'm shocked. I'm on vacation in Michigan (arapaimas are illegal in FL) and I went to this fish store, Oceans and Seas, and I saw a completely black Arapaima!!! It was about 6-7" and 225$. Im still trieing to get a pic up I got a crappy one on my phone... So what is this thing, melanistic maybe??? The guy at the store said it was being beat up by another fish so they moved it to a different tank and was treating it. The black is definetly not caused by stress because it is black as hell, like it was dipped in a black sharpie ink. Is this thing worth anything, is it worth buying??? Like I said I'll try to get pics ASAP.
