I recently found my favorite fish, a powder blue tang, laying at the bottom of my tank obviously near death. I scrambled around testing the water and concluded I had let the salinity get too high from evaporation. (Normally around 1.025, now slightly above 1.027.) I found no other parameters out of normal.
Even if this wasn't the ultimate cause of death (he finally did a few hours later,) it raised questions as to what I could do if I find a near-death fish again. Here are my 2 questions...
1. What are all the possibilities...what can I do with a near-death fish that gives the best chances of survival?
2. If I do decide to move him into a seperate "hospital tank" should the parameters be any different than the show tank? I have heard fish prefer a lower salinity closer to 1.020....but would the shock of the salinity change do more harm than good?
Any help is much appreciated!
