Hey guys! I haven't posted in a while, I've been busy.. Nettle has been biting his tail more and more lately, but I can't figure out why. e.e I tested his water and the levels are all normal. It's not shredded from a decoration, because I've caught him biting it twice.
Any thoughts on what else it could be? He's in a 5gal by himself.. Everything in the tank seems fine, he's eating fine.. I just can't figure it out. I literally change part of his water almost every other day because for a while it seemed like he was biting because of the water quality, but now I don't even know.
e.e Thanks in advance guys.
