ok the situation is this.
The tank is a 1700 gallon system with loads of fish in it a a few corals. All parameters are good with NItrates just showing a bit high at 40 but should be no issue looking at whats in the tank I believe.
The tank has been doing very well for about a year now (for detailed fish list you can check out the build thread of this tank here in RC)
So all fish doing realy well and eat like crazy look fat and all.
Friday I have a batch of dwarf angels for another tank and see I have one in overtall for that tank so add 1 yellow angel to the large tank. on Saturday we add 1 leather finger coral and one leather mushroom to the tank and all is still good. Now MOnday morning with feeding we see fish are not feeding as normal and we see one of our powder blues stuck on the overflow ready to die so at further inspection we see many more fish struggle. Tuesday we remove 2 death butterflies, 2 death anthias Wednesday we see most tangs start to feed again though still reluctant and much more skiddish as they used to be hiding in the rock all the time only 1 death clowfish seen. No today Thursday we film the clip of a clownfish struggling and have 1 more anthias lying on the floor as death though when caught it was still alive though we removed it anyway as it is dying.
On non of the fish any sign of Ick or any other skin lesions I think. The clown in the clip as maybe not really view able the skin looks like dry and rimpled and seem to have melted skin on his back fin?? in the clip which is filmed on the side (so top of tank is actually left side of the view) the clown goes up to the surface to let himself sink back down over and over again. All other fish seem to be behaving the same as last few days feeding reluctant and still hiding all the time??
what could be wrong and what disease did I clearly introduce into this system though the Yellow Angel (can a disease from 1 dwarf angel small size even spread that fast??) or through the rocks of the coral though they came from my own system and have been doing in an ok tank for over 3 years now.
anyone can help so we know what to treat tank with if treatable? large size of the tank does not help the situation here for sure I think
