Hello,

I have had loads of tiny things on my glass for a week or so now. Some of them look like spiders and others only have 2 ‘legs’. They are easily removable with a scraper.

Last night I noticed something in my Zoa frag that I thought looked like aiptasia. However this morning it has completely disappeared and there is nothing at all there where it was.

I have soft corals in my tank which I introduced about 2/3 weeks ago and I’m really concerned it’s aiptasia.

Please can someone help identify it? And hopefully tell me it’s not aiptasia

Thanks in advance

What is on your zoa looks like aiptasia

Would it just disappear overnight? It has completely gone and last night was the first time I’ve seen it
