I do agree that test kits, if you don't already have them, should be priority; way above and beyond more fish. So many fish health and stocking issues depend on proper water quality that no fishkeeper should be without a decent (liquid or tablet) set of test kits.Wansui said:To know for sure I would advise you to buy a master test kit. This tests for ammonia nitrite nitrate, PH and high PH. You need to be sure your tank is cycled, for the welfair of your fish. Until then I can't in good conscience suggest to you any more fish.
