Hi all! I have been keeping freshwater fish for a couple of years now, and recently I have been interested in saltwater. The tank in question is my friends brothers old 15 gallon biocube tank. I am getting a sick deal of 20 dollars for the tank and stuff that came with it. Only problem is the bottom panel got busted due to a pressure point on the table. So I will have to replace that, (and have the tank sit filled on the garage for a couple of weeks to check that it holds) then I will be in business! My current stocking plan is 2 clownfish, 1 goby/pistol shrimp pair, and a basic CUC. Is this full for a 15 gallon? Or could I add more?
