For some reason my tusk is acting like he can't see well or is going blind. He was the most aggressive fish in the tank and would chase the Blue Throat Trigger away at feeding time.
But now, out of nowhere, when I feed them, he chomps at open water completely missing the food. If he apots a big piece, he goes for it but quickly loses sight of it. I have to put half pieces of krill in there so it's big enough for him to find it.
I've had this tank setup for almost a year to the day and he was the first fish in it.
What could cause something like this? I mean he still has his juvenile markings on his top fin, so it's not old age. All his tank mates are all fine and there's been no new additions to the tank.
Any advice would be greatly appreciated as to what this could be and how to treat it?
