What did you use for the paint for the back and on your overflow?
I like the black vs blue background, think it looks better when coralline starts growing.
Only 40b's. One is slated for a cichlid tank. The other is for a frag tank setup along with the 50b. Thinking about a couple more 40b's. Also looking at the possibility of breeding.
Though I do love some of the South American cichlids, my favorite are African cichlids. Used to have a few breeding pairs and I miss that so I want to get back into that.
