Fish Fanatic
I've been keeping the lights off in my 10 gallon as when i switch them on, Rocco (my only betta) swims up and down the length of the tank at the back flaring - i'm guessing he can see his reflection. I've tried this without the background and he does the same thing. I'd like to leave the light on during the evening so i can see him, but i don't want him stressed out or flaring too much (is that possible?). Would it be ok to leave the light on like this for a few hours at a time?
