Hi mate, yes it's floor tiles I've used. Thought it'd be a change from the norm. And 3x 305 fluval external filters running too along with a wave maker to keep surface water forming any film on it. I've now added a couple of realistic plants to it to add some breaking colour.
My other tank has 2 baby Red Tiger Oscars in it which I've had since they were about an inch in size and are now about 4-5 inches long now.
