I know, he's adorable! I was surprised when I didn't see external gills...they must have just lost them and then shipped the poor things. He was housed with a bunch of albino tiger barbs and 6" ghost knives! I saw the barbs picking on him and I had to save him haha.
Update: So I fed a few frozen brine shrimp and blood worms, I didn't get to sit and watch because I had to do something, however the bottoms looks relatively clean...I just put a very small piece of earthworm in there, he found it and after snapping at it a few times, he grabbed it up and ate it, so he seems to be improving!
