[kimiki]

It all heppened a few weeks ago!
Over the night, my 2 years old yellow tang and few anthias were dead

All other fishes are all right, corals are fine, parameters are excelent.

After 10 days I bought new one. This morning I finded him dead to ?

Does anyone have any idea obout those events pecouse it is frustrating ?

All I can think of if there are some contaminate in the tank that we do not test for. Or it could be you just got an already sick fish and it's death is unrelated.

Welcome to the forum kimiki. Can you fill us in with your tank info. There's a button in your post that says "my tank" click that and give us the specs of your set up.

Also, can we get your current water parameters? How long has the tank been up and running? All this info will help us narrow down what might be causing the deaths.
