I was given someone’s setup to take care of consisting of a couple live rocks, 2 clowns and a frogspawn coral, I noticed a good handful of small aptasia on one of the rocks so have removed it and boiled it and it’s currently sat out in the sun so hoping it’s done the trick! I do appreciate it means I have lost the beneficial things living on it but there were too many and I thought they were isolated to just that one. This morning I have noticed some small dark things on the plug of my frogspawn and I wondered if anyone can identify if they are new aptasia starting or something else? I’m completely new to this so would appreciate any help in what they are and how to get rid of I need to!
