great, thanks!

Glass catfish (Kryptopterus minor) probably don't get fat the way other fish, even other catfish, do I'm guessing? Whereas most fish will lay down a layer of fat under their skin, I can't imagine glass catfish have any room for fat deposits under their transparent skin.

So I have noticed that my ...

No problem, Marc. I know it's not obligatory, but I thought it would be nice if they COULD rest once in a while.

However, when I was ...
