Its a catfish. And over all that, its a fish. If he is stress free, which sounds like he is. Not getting picked on and stuff. Then i wouldnt worry about it. No fish is gonna kill itself from starvation unless something is wrong like stress. He will eat eventually. Ive heard that sometimes they just have to warm up to you. Not comfortable enough yet. Not sure if its 100% true, just something i heard. But once he does start to eat like how he is suppose to, man, you have another coming. He will double his size in no time. My rtc is like 6 months old and 18" now. Goodluck! hope he eats.
