Hello everyone. I start my tank 6 months ago and 3 months later I have to treat it by cupramin seachem because of ick problem and nothing added to my tank after that. From 1 month ago this little string start to grow out of my live rock. Can anybody tell me what is this small white strings on my live rock that I send in first and second images ? Maximum Size of them is about 3 to 4 millimeters and mostly growing on light spot.
And in second image what is this creature? Is that Aiptasia
