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
