My Betta Harley recently got a new home (10g, heater, filter, decorations, etc). He's currently suffering from fin rot and the water chem is good. Aquarium salt is being added for the fin rot.
He's been in his new tank about 4 days. Its taken him a while to get used to it I think, but for the most part he got more mobile yesterday afternoon. When I got up this morning, I noticed he was ramming and bumping the side of the tank presumably after he sees his reflection. At Petsmart I've seen fish "wallpaper" for the tank back (not sure if it does sides too). Is this a worthwhile investment to help him stop ramming the tank/reduce the reflection, or should I even worry about it? I do have a birthday card I got on that side of the tank but it was on the back of the tank before I moved it and he didn't ram there, and beside his old bowls (1 gallon bowl traditional style a 1 gallon round bowl) the card was there with no problems. I just don't want him to get a concussion
I've heard of other fish doing it on here but when is it too much?
