hi all,

in the first photo... I know it is small but could these be tiny aiptasia?

in the 2nd is this some sort of chordata. it was on the back of a monti frag i bought. is this a bad thing?

The first pic looks like little feather dusters. Def not aptaisia. They are good filter feeders and will most likely stay small like that.

So. Tiny stinging jellyfish dont sound so good. They are only on one rock right now but spreading quickly. Should I try getting rid of them or let them be? By the way can they hurt us w their sting?


Thanks. CcCapt!!

Get rid of them. I'm not sure what the best way to get rid of them is, but I'm sure Google can help there. You will want to remove that rock asap, though.
