I am pretty sure I have found aptasia just one so far but I am hopeful that I have nipped it in the bud and if I kill it it might be the end of it as I had already quarantined two Coral that were looking a little bit sick about a week and a half ago and last night I noticed on my hammer there was one head of aptasia which was not bought that many weeks ago so maybe it was just grown is it likely that I have beaten the problem by accident, and how long do you think it will be before I know for sure six weeks or more if don't see any can I be confident
