Hi guys. I need help. I am getting fish soon to stock my 15G tank, but there is limited space. It's an AIO tank, so the sump is on the back, which is probably around 1.5G. One thing I can say, I added just over 10 gallons of water to the tank, with rock and sand. So very limited space. I am definitely going to put a pair of Ocellaris clown fish in it, as well as a scarlet skunk cleaner shrimp, and a small CUC, (less than 10 inhabitants), I was wondering if when I do get fish if I could add another, and more specifically a firefish, and if that would work well. I don't want to overstock my tank, and I don't want any fish to get bullied by the clowns. Thanks for your help.
