He has been eating like a pig, he looks fatter now. He's eaten three of those fish since i put them in there for him. I have the axolotl pellets and frozen bloodworms for him, but those didn't seem like enough, bc like u said he is skinny, so I got him some feeder fish to eat (from a small mom n pop shop where I know the owner personally). I don't think the guy I bought Dobby from was feeding his axolotls enough. They all looked hungry. I'm workin on it though. He is one of the gfp colored ones.... Not sure what kind of bulb to put on the tank, I have been looking around for one. I looked for an axolotl that was big enough and seemed pretty healthy, nice gills etc for about 6 months to even find him... and I have done a lot of reading about them as well. Not saying I know it all (cause I definitely dont!) but I sort of know the basics. He is the first axolotl I have had! (btw... the first pic overhead was the day i got him... he is rounder around the middle now... about as fat as his head is wide. Ive had him almost 2 weeks.)
