I know how ridiculous this sounds... but when I have my hands in the tank, my two glass catfish will find a plant and lay in it. They'll lay completely on their side. About a minute after I'm done they're back swimming next to each other. I've read people saying that is likely an issue with their swim bladder... but I've been watching them a lot since I got them (recent) and they only do it when I've got my hands in the tank.
Is this a thing?
