Reefing newb
Our Yellow Tang died, and then 2 days later our Ocelaris Clown died. I don't understand. I added a new powerhead to the tank, and I did a small water change the day before the tang died and also tested the water. Everything was fine. The Yellow Watchman is fine, and all of the inverts are doing very well. I now have a whole lot of teeny tiny tube worms ( I think ) all over the rock and an arse load of spiroids ( Sorry if the spelling is wrong ) all over the glass, so I assume that my tank is healthy. Any ideas as to what the hell happened?
