My 7yr old son caught a yellow bullhead catfish on his birthday 8/24/08 and he did not want to throw it back so we kept him, he is about 8" but the problem was i did'nt have any space for him i put him in the tank with my 17" black hoplias but you know what happen, so i had to hurry up an take him out, so the only other place was in the tank with my 19" umbee i know you guys like why would he do that , but they have got along good since then. the bull head is during fine an i will have pic's up soon of them togather. oh! he caught him in the potmac river
