This tank is not a new set up just new to me . Was baught by my wife. She had the girl who owned it set it up. It had some live rock ans live sand 2 chromis 1 skunk clown 1 purple Psuedo. fish only 15 watt light. Very cheap hang on filter. I added 130 watt satelite compact some already cured live rock 20 lbs live sand and tank has been in my house little over month thats why i wated to add few fish. The cromis were only 1/2 inch long they all came up missing 11/2 days. only have skunk clown in the 25 gal right now snails and crabs also.
