Help. I have 4 fish in a relatively new tank. Male and female clownfish and fire fish and a hi fin banded goby with his shrimp. I find the male clownfish with tail missing then he is acting not well and disappeared then find female dead no signs of being attacked . Can't find body of male clownfish. Fire fish I have never seen him being aggressive and the hibfin goby saw him nip once the fire fish but he normally just hangs out at the entrance of his hole.. I can't figure out why I have two dead clownfish. No nitrate no ammonia and 10ppm nitrate. 32g biocube
