Fish not looking good.

So a buddy of mine recently setup a small tank (40g) and has had it running for about a month. The rock and sand were all established (from my tank) and everything was good.

He put some clowns and chromis earlier this month. He added a flame angel about 2 weeks ago and just recently bougbt some rocks with zoas on them. Yes, the angel has been picking on the zoas.

He woke up to a dead flame angel and the clowns arent looking good. The chromis, and a cardinal, are all looking good though. There doesnt seem to be any signs of ich.

He recently did a water change using Scripps this past weekend and his salinity is good. Any ideas to what may have caused this sudden change? Fish were all healthy yesterday.

I know zoas can hurt humans, but would they be able to affect the fish as well?

What are his parameters has he checked ammonia, oxygen levels any irritations or lacerations on the gills or body.
How big of a water change?

So i just went to take a look and the clown are rough looking. Looks like their skin is falling off. One has a weird scar on the back towards the top fin.

Velvet?

Yeah, thats what im leaning to. One clown is gone now. We seperated them and will keep an eye on the rest of the fish.

If the skin is peeling off, its like brook.

Google pics of brooklynella and see if it looks the same.
