So ive had a blue tang for a while now, About 4-5 months. He/Her is doing really well, Only problem is. Lights go out, So i turn the LED
moonlights on, Kinda like 2 spotlights over the tank. It doesnt light the whole tank up, Just 2 sections, And when i have them on, He stays in his cave and sleeps. If i have them off, Its like his lost.. He swims on the surface of the water and splashes about. And if he wakes me during the night, Ill turn them on and he goes into his cave.
His a funny little fish. But just curious whats causing this? Or its just him? All the other fish sleep if its on or off.
