Any help appreciated. Looks like some type of worm.

annoying pest anoemone.

Get rid of them by natural means or you will be fighting a losing battle. Buy an aptasia predator.

What eats them?

 

[d5332]

Berg Nudibranch (will die once it eats all of them, does not eat anything else)
Matted Filefish
Copperband Butterfly
Peppermint Shrimp

I see a clam in your pic, you need to research which of the above is right for your tank and the livestock you have in it.

If you dont kill aptasia in 6 months you will have a tank cover from top to bottom in aptasia, you should probably read up in aptasia as well.

I like the copperand butterfly but will they also eat corals?

I have had Copperbands and none have ever touched any corals, my last one was close to 3 years old and I lost it when my tank cracked. If you get one make sure it is already eating in the store. Also what size tank do you have?

I have a 46 gallon

Thanks for the messages.

Will read up and get rid of it.
