Help ID these things

[2peppers]

Hey. I'm new to this forum and relatively new to saltwater tanks. I have a 29 gal biocube that I bought from somebody on Craigslist about 6 months ago. He had it running for 4 years. It has all kinds of little hitchhiker critters that I have found all to be good. There is one that is spreading like wild fire tho that I can't find much info on. There's probably 100+ in my tank. they look like psuedocorynactis to me but everyone says those aren't a problem. These things are everywhere in my tank that is out of direct light. They don't seems to bug my coral but I wanna know more about them and how to irradiated them without using aphasia X because that would take months. Thanks

ball tip anenomes

You feeding the tank a lot? Usually they're fine and not an issue. They tend to hide in dark areas but are known to sting. I'd try to lower your feeding if you can.

Yea I tend to over feed. I have a greedy little cleaner shrimp that eats all the food before anyone can get to it. Forces me to over feed so my fish can get some too. I might have to get rid of him. Thanks

Anyone know of anything that eats these ball tip anems?
