Thanks, all! I saw him and just fell in love!
I'm guessing with his gill problem I'll need to have decorations with no sharp edges AT ALL! I don't even think I'll be able to use silk plants!
I'm afraid something will get under his gill and do some damage inside. I've already decided that I'll need to take the decoration that's in there out because it might have sharp edges. I'll just have to get a nice hide for him that doesn't have any weird edges. For now I think I'm going to put a mug in his new tank for him to hide in.
His new tank is a bit tall and I was wondering what I could put near the top for him to rest on if he wants. I've seen on a few pics that some people have a fake plant with a suction cup attached to the side of the tank. Can you buy those like that, or do you have to make them?
