I got my first yellow bullhead back at the end of June at around 3.75-4" because all I was hearing about them was that they are extremely active at feeding time and often cruise the tank and surface feed once food hits the water. Well at this he's about 7" and shows none of those characteristics. He never leaves his cave, won't surface feed, and won't even come out of his cave a few inches for food that floats in front of his face. I have to hand feed him every night directly into his cave because he can't get food other ways and the farthest I've gotten him to venture out for food from my hand is about 3" with just his head sticking out. I have no idea why he's like this and it's not typical bullhead behavior at all, I'd like to get him to be more active so if anybody has some suggestions feel free to say them. I also know he's not acting normal because I'm growing out three 2.25" yellow bullheads in a 5.5G (very temporary tank) and they're out swimming all day as well as handfeed from the surface during lights on, they approach my hand as soon as it hits the water. I've had the little three since they were 1.5" and I think maybe the size I got my original one at (4") may be the problem with him not being active but I have no idea.
. I did get him to come out about 6" two nights ago though so maybe a little bit of progress there. I had my hand out 9-10" and he came out 6" so he could vacuum shrimp pellets from my hand.
