The Glass catfish is a schoaling fish; meaning it likes to school. If you have room in your tank, you should consider getting at least 3 more. Because it is a schoaling fish, if it is in a tank on it's own it can become stressed out more easier which can lead to bacteria infections in your tank. Be sure when you buy fish that you learn which are schoaling and which aren't. I have 4 glass cats in my tank and they are always together unless it is feeding time. I also have xray tetras that they schoal as well.Hey,
So I recently upgraded to a 20 gallon and my glass catfish and halfbeak have been hanging out a lot together. Anyone ever heard of something like this?
Thanks,
Tim
