This was the biggest yellow bullhead by far Id ever seen had him for 2-3 years then he died one weekend while I was gone (RIP) I was super sad because he was huge and gentle for the most part. I would put a bunch of minnows in my closed hand and he'd swim up to my hand where the opening was and just open his mouth and suck them out. He never killed any of the bluegills he was with he did try though. They're my favorite fish and I definitely want another big one to replace him.
