View attachment 3965Hello everyone!Details :28 gallon BioCube Salt Water AquariumI noticed in 2 month all of my 4 fish had totally disappeared. The only thing I can think that’s new is recently these worms have shown up (in picture). I don’t know how many there are but I’m afraid there may be a lot.I miss my fish and so I want to get more, but I’m trying to figure out what is the best way to get rid of them. I have sand at the bottom of my tank and I’ll totally replace it but what about my LIVE ROCK? Is there a way to ensure it is free of any critters? Or should I start all new with that too?Please help!
