Sooo. My friend and I have discovered another way to excessive/entertain your fish. She recently got her first better, which she's been keeping at my house, and wrote his name on the side of the tank in dry erase with a fish drawn next to it. Needless to say he must not think its very funny because he flares at it.
Obviously don't put it inside your tank, but on the outside glass, they can see it. I've done it to the rest of my boys tanks, they're either investigating or flaring at it. We'll see how this goes, AND it is something that can change constantly, colors, shapes etc..
