I was treating a yellow tang awhile ago for a host of problems. He was doing much better and the hyposalinity really seemed to be working. The freshwater dip also went well. Anyways, I came home one day and found that my heater stopped working. The tank was 60-65 F. Sadly, the tang died. :(
Also, I never had any problems with my 46g. When I moved here I got a 72g and a 24g and have had a host of problems.
