Thank you, guys.



Those are cool bullheads. Thanks. Most max sizes say on PCF are subject to change and anyone can effect it by sending in the evidence - a photo of a fish with a measure tape next to it. While these cats are indeed relatively huge, it's hard to gauge as the anglers are doing their usual cheap trick. I wish they haven't. Or much rather, I wish they included a measure tape in the shot.
Good call, I didn't think to account for the fish being held at arm's length...
I did some digging and couldn't find any records of truly giant snail bullheads, although here's a picture of a pretty nice one (with tape included).post-4799-0-15156400-1451515210.jpg

Nice! Thank you for that. It's right on the max reported size:

... Remember, the champion / max reported sizes:

-- black -------------------------------- aka Ictalurus melas ~~~27"
-- North American white catfish - aka I. catus ~~~~~~~~~27"
-- brown ------------------------------- aka I. nebulosus ~~~~~~23"
-- yellow ------------------------------- aka I. natalis ~~~~~~~~~19"
-- snail (I think aka spotted) ------ aka I. brunneus ~~~~~~~15"

Update on the two southerns. Not much to say in words. They are about 12"-14" now and it feels like they have not been growing. They got ill when I had an outbreak of something (maybe columnaris) in 2018 but recovered.

Do not house pacu with bullheads, I'd say based on my experience. The same as occurs with channel catfish - the pacu bite off pieces of their fins as they please. Looks like they do it for feed. Had a pair of 1' pacu come in as rescues and placed them in this 240 gal tank. In a few days, the bullheads stopped swimming around and their fins, especially the dorsal, were reduced by half.

Looks like pacu and these Ictaluridae do not mix.
