my fish keep dieing but my coral are super healthy need help idk why i lost a naso a sailfin tang a pink squared anthias and a pair of clowns my levels are perfect on point my skimmer broke a few weeka ago and i also found these worms in my sump im clueless

 

[coralcruze]

could you post some params? is it possible ich is present? look at salinity and temp. skimmer broken can bring the ORP (disolved oxygen) real low. do you notice any fish gasping for air at the top or gills moving rapidly?

Could be ich or velvet. Corals wouldn't be harmed but fish are different story. What did fish have on them before you removed them ?

It's that damn SAILFIN TANG

There are a ton of different reasons why your fish are dying. Many of them you won't be able to test for. Are the fish eating? Do they look healthy? It might be an internal parasite. If I was you I will dose Prazi wait a week and throw a UV on the tank. Unless you want to take all your fish out fully treat your fish for everything and leave your tank fallow. Use Furan 2 as an antibiotic and treat with prazi. You can use copper if you choose to.
