Purposely growing algea on one side of tank
I have a Six-line Wrasse who either gets very aggressive or horny, I'm not sure which, when he sees his reflection! ( his eyes actually go red!)
I have to put paper over the side of the tank to reduce the reflection as this side of the tank points to a dark corner.
Would it be wise to allow algae to grow on this side to stop the reflection, or would I just be creating a lot of hard work for myself in the future?
