Thanks ChuChu1,Texan,and Bob for the replies.
I have had bass on numerous times chase hooked Bluegills.
I have even caught a few very nice bass on hooked Bluegills.
I have seen big Channels chase a hooked sunfish only a few times over the years but never a Channel Cat or any other catfish chasing a Rio.
I do know that Rios especially the small ones make GREAT catfish bait especially if they are alive.
