My 8" tilapia buttikoferi has been acting strange lately. He'll swim really fast from one end of the tank to the other to scratch himself on the gravel, and his coloration is very dark. Also, he will sometimes twitch, I just observed it on his top fin, but most of the time it will be twitching his head from side to side.
He's in a bare 55 gal with only gravel and a few small stones by himself, 80 degrees, 2 fluval 4's, and a emperor 400, and all water params are normal. He has had no tankmates since he was 1.5". He gets a 50% water change once a week after which I add water conditioner and aquarium salt.
I've treated him for parasites with this:

What do you think it could be?
This is my first sick fish and he is also my most well-cared for I really don't want to lose him.
