Losing fish after adding new nems need help

[andrewjames]

Have had my tank for around 6 months no dramas so far 2 clowns damsel dotty back zebra moray eel and copperband have goni coral ect
Lost copperband and my big clown heavy breathing on the copper laying flat no orientation
Had red blemishes on him all within 15 hours off adding nems to tank water ph nitrites nitrate salt ammonia on point

If a infection to dump the tank and refill or quarantine in smaller tank only issue with quarantine is the zebra moray is 4_5 feet any help on best way to go about this on Christmas. Or to put in my ro tank is 200l

Welcome to Reef2Reef!

While anemones are well known to be able to carry fish diseases from one tank to another (due to the water volume they have inside their bodies) I cannot think of any fish disease that can enter and aquarium and cause acute disease issues in only 15 hours. Velvet is the fastest attacking fish disease, but it takes 3 days or so for the infection to build. Ich takes longer and flukes take longer still (weeks for ich, months for flukes).

What species of anemone did you add?

Added a red and green bubble tip anemone, a goni and this to the tank pic

did put the a damsel and the clown in the ro set up that was ready for a tank water change last night as seemed stressed in the tank seems fine this moring eel and dotty back still in the 4x2x2 seem OK in main tank. Any thoughts on process from here I have enough water ready to go that I could do a 75 percent change

Those invertebrates would not have caused the acute deaths like that. If your water is testing good, I don't see how a large water change is going to solve the issue.

I'm stumped, unless the adding of the anemones was just a "red herring" and the fish actually had a gill disease leading up to that point, but the symptoms just weren't clear enough for you to notice.

Yeah that's why I've been so stumped they have seemed so happy lately and even everything getting along. Just really bummed about it as the copperband has been a great fish
