I have been searching the net for help with my marine tank. We have ran our salt water tank for 10 years now with no problems until lately. We lost our fish a few months ago and have 4 blue damsels and a clown fish left. Every time we try to add a new fish it lasts a few days and dies. They get some type of film on thier entire body which covers thier eyes and everything and within a day of getting the film they die. We have done all our water tests and changes and are at a loss here. Yet the damsels and the clown are fine. The fish also loses all its color at the same time.
Please help
