What do yellow bullheads do to their cousins that prompts everyone to say that you shouldn't mix them? Just curious.

Because the yellow bullheads will chew other bullhead's tail to its death. Yellow bullhead are much aggressive than black and brown bullheads. Yellow bullheads will test other tankmates to see if they can fit in its mouth or not. If not then its mostly will ripping their tails or half body off of the other bullheads. 2inch yellow bullhead had no problem to kill 5inch mudminnow by just ripped the tails or grab in middle body or mudminnows which that is why i dont like yellow bullhead so much that they must be in species tank only, not even other catfish such as pleco or channel catfish.

They're that insane? Jeez, I already thought that bullheads were already pretty rough and rumble fish, but it seems yellows dominate this area, at least for bullheads.

I have kept young of all three of the common bullheads together, with no troubles. I mention young, because I had not kept them all that long. Possibly individuals of yellows are "killers", while most are no more aggressive than blacks and browns.

I believe just keeping them well fed would alleviate most troubles with this kind of aggression, outside of spawning.

Agreed, Personally I have never noticed a big difference in the aggression/temperment of all the Bullhead species. Like choupique said I definetly think that individual tempermant varies tremendously from Bullhead to Bullhead. I have kept Yellows Bullheads that are from the same "litter" and they will have very different tempermants.
