bad that I totally thought we where talking about a feather fin betta? 😂As the above comment asked, what fish are with him? If you have aggressive tankmates he'll try and hide a lot so he may be better placed elsewhere if this is the case.
Many catfish do like to hide so it may be worth finding him a nice piece of wood or cave to hide in.
They can get very large so if you keep him I hope you have a good size tank They can get up to a foot long.
Lovely fish the featherfin squeaker
