I have an Elos aqua top which cover most of the tank. There are 4 opening on the sides like a semi circle. Any one have any good suggestion on how to cover these and still let the air flow.
If your jawfish is jumping maybe there is something that is spooking it or something out of whack, I know fish jump but sometimes it can be for a reason. The egg crate works well, you find that in the lighting section of your local home centers.
