I've just put a black binliner on the back of my divided tank, it looks ok , hides the air tubes and wires but Sirius is flaring a lot. He can probably see himself somewhere, but is it dangerous for him to flare a lot?
Also I have put some of my larger guppy and molly fry in the other side , to see how they like it. LOL.
