Looked in my tank yesterday and noticed my sail fin died. I also have two clown, a yellow tang and two damesel.
Don't understand what happened, all was going well, had the tank for 6 months now 45 gal
One thing I did notice was that the fins were damaged, like tears in the fins? I never seen the fish fight, on the contrary all was always good, but could it be what happenned? I checked nitrate, trite, and ammonia, all is good.
Also I had done a 20% water change just last week?
