Ok, I had 5 fish in a small quaranteen (sp?) tank in a hyposalinity treatment for ich. When I went home for lunch there was smoke pouring out of the top of the tank. The heater has broken and there is black stuff all over the bottom and floating all over the top of the water. I removed the fish and put them in a 5 gallon bucket with a heater and pump but three of the fish are not looking good. The Royal Gramma looks the worst of all. Obviously I'll have to setup another tank when I get hom but is there anything else I can do to help my fish recover?
