Fish attacking reflection

[Shawcabelguy]

I cleaned my glass yesterday for the first time with an magnet scraper and it's real clean but now my yellow tang looks as if it's stressing itself out by attacking it's reflection lol any thoughts on how to stop this?

Reefers all over the world would like to thank you for providing an excuse to not bother to clean the glass! Seriously though, I would continue to observe and monitor the fish. Is it eating? Is the clean glass unusual?

I just turned down the lights and put my lights on and put a white piece of paper by the tank where he was attacking but she's still going a it in other wpors. And no never really gave it a good clean before yesterday was the first time in months there was some good brown algae allover lol

If you can see thru the glass, why do you think your fish can see his refection?

 

[Shawcabelguy]

Not sure but he's definitely attacking the glass maybe not his reflection but something lol

I have flasher wrasses that definitely flash their reflections. As if they're showing off to another male. In my case it's a good thing.

My regal male and my bicinctus fight their reflections in the glass all the time. It's usually more in the evening when the lights go down.
I take it as a good thing as it gives the fish some excitement and an outlet for aggressions.

Well hopefully it doesn't stress him out too much and he chills out lol
