OK for lack of being able to take a good picture...in my refugium 2 things
have popped up.

1. Look like clams stuck to side of the glass. They don't seem to ever
move and their soft and white on the inside. 1 sided shell.
2. Found floating in my Cheato...some sort of anemone looking thing.
Doesn't look long and stringy like Aiptasia...but
It looks to have many arms with a base and little light purple tips.

Any Ideas ?

Thanks...Hurry cause I got my exterminator mask on : )
