Thanks for the quick reply...

I have like 4 of them in my tank... They are the size of a dime... So they should be ok to keep right???
 
really depends on your lighting and how long your tank has been running. Anemones are fairly light intensive and need an established tank that has had stable water conditions for several months
 
its a 75 Gallon w/ PCs... been running for a year now as a fowler... am getting ready to upgrade...

I just want to know if I should take them out or if there ok... would also like to know what they are...
 
It looks like a BTA to me as well. Although I've never seen them that small. Anemones usually split, not spawn. Try lightly touching it with somethin like a feeding stick to see what it does. If it retracts back into the rock from which it came it is highly unlikely that it is a nem.
 
Smitty is right. Definitely majano anemone. They will wipe out your livestock, so get rid of them ASAP. You can use Aiptasia X to kill them. I had my old 240 over run with majano. I started with one, and they quickly multiplied in the thousands and killed every coral they touched. I ended up having to boil 500 lbs of rock to kill them. And I still get them popping up from time to time on the old rocks! They are incredibly hardy, and really horrible pests!
