ARRRGGGGHHHHHHHHHHHHHHH

We moved the chichlid tank from my moms house to our house. It has been a week. Came home today and all the zebra cichlids, the cobalt blue, and a bumblebee fish were dead. The convicts, pleco, and oddly enough the parrot fish are all ok. Tested and found high nitrites and no ammonia - damn - I figure it was because we used well water and no conditioner? RIP guys...
