Just a word of advice to make sure you can reach the entire bottom of it. One of my fish decided to brute force itself through the cover yesterday. It thought the gsp was greener on the other side. In an effort to save it, I put it back in the tank hoping it would survive. It didn't...and it wasn't easy to get to it. I have decently long arms. It's a 3'x2'x2' tank and I couldn't reach the bottom middle without forceps.Thanks! I just wish my tank was about 6 inches wider and longer so I could space things out a little more. I'll probably upgrade the tank in a couple years to something similar but a bit wider and deeper.
