I’ve had this blue eye kole tang for about a year. I got it at about the same size it is now, maybe a little smaller.
No glass surfing that I can remember for the first year. About a week ago it started doing it. Very intensely, at first on and off but now it’s an obsession and it’s going on pretty much all day, frantically. Even when the lights are out. Lights have been off for 45 minutes now and it’s still doing it. Only on one side, the right one.
I’ve been keeping fish for decades but I’ve never seen anything like it. I’m wondering if it’s caused by the fish reaching sexual maturity ? Or maybe too much rich food (I feed frozen twice a day + another feeding of pellets or flakes) ? I know in some animals abundance in food might trigger reproduction and aggressive behaviors.
I’ve tried covering the glass with a dark cloth, white cloth, egg crate, white film. Nothing works.
I‘m afraid the fish will wear itself out and get sick from disease and parasites. And stress other fish as well.
Any ideas what I could try ?
Thanks !
