So I am swapping to a new tank being careful of what gets put in. Went to move a hemit in a snail shell and found this in the pics. any idea what it is ??

Looks like a Nem of some sort, gotta wait for the culprit to show himself.

honestly this is the sump form a tank that crashed. the crab has been in the sump for about 3 weeks I just happen to notice this. I have rock nems but, I know they spit out young I was thinking a nem but it looks to be growing like zoas the two are attached

Yea, I thought Zoa first, but never seen a Zoa split like that, so next I thought a splitting Nem. But, I'm guessing.

Only nems I have are rock nems. I have not had a condy for 6months so I wonder what and where this came from to still live through the crash and show up now
