Hi,
I noticed on Thursday last week one of the fish (yellow tang) I bought a month ago out of nowhere just died. Then I saw my blue tang had white spots on him. I started treating with melafix. I don’t think it is working. I have the following in my 75gallon. I don’t have a quarantine tank. None of the other fish have spots. The blue tang is eating and swimming as normal. I had my water levels tested last Saturday they were all in normal range. What is the best way to treat and without killing my corals? Thank you In advance.
2 clowns
1 sand shifting star fish
1 damsel
1 diamond golby
1 tang striped brown and yellow
1 blue tang
1 yellow wrasse
1 snail
1 Xenia coral
1 coral I forgot that it is called.
The first two photos is when it started on Thursday. The last two photos are from yesterday.
