So I had to run out and bought a 10 gallon tank to separate my Chocolate and Purple Tangs that were in the 29 gallon hospital tank (which was going to be a seahorse tank - not anymore). They’ve been in Coppersafe for going on 3 days now. Tested with Hanna Cooper device and levels are were they should be. Both Tangs are eating but covered all over their little bodies. The Purple started out the worst and I am worried about her eyes. It looked like they were shedding. They seem to be a little better (fingers crossed). They both are eating and swimming around.
