False Tigernose Catfish

If that one is an unusually ugly looking case, then yes. The one at the store looks much better.

I think that is a nice one.

I think fish can tell "suitable environment" (such as water temperature) to some extent. However, I don't think they feel "pain" from heat, and as long as the water itself isn't warming up very much, the fish aren't going to feel the burning sensation when they "park" next to a heater. That's my thoughts, but as I said, I don't know of this from some form of actual understanding of nerve physiology on fish.

I will try to see if any of my scientist friends know...

Thanks Mats! Looking forward to your possible findings or perhaps someone else could point me/us toward a useful webpage... ?

They probably follow oxygen saturation more than heat. But since hot water holds less oxygen, it seems like they are avoiding heat when they are really just pursuing better breathing grounds.

It seems we know very little about fish and pain... This is about the only article around, it seems. I guess there is a paper in a journal behind that article, which give a tiny bit more information, but I doubt it's really that much more ...

ANd yes, I think following oxygen level is more common...

I do agree with Jurenese. However the store keeper should have it labeled as "False Tigrinus Catfish" not Shovelnose IMO.
