what are these things growing in my tank?

[coryhupfer]

Well it started with just a few and now they are starting to take over my tank and I dont know what to do.it is starting to mess with some of my corals and I need to figure a better way to get rid of them without just plucking them out because it is extremely hard I try to with my feeding tongs and they always just go back into the rock before I can get them I can sometimes get one or 2 of the big ones but I dont know what to do about all of these.any help or info is appreciated

That is Aiptasia, do a quick search on this forum and it will give you several ways on getting ride of them. Start now before it really gets out of hand.

Aiptasia. You need to eradicate it ASAP. Chemical treatment includes aiptasia-x or you can try some peppermint shrimp.

My lionfish would probably eat the shrimp ill goto the store tomorrow and get some stuff to treat it thanks for the quick responses

+1 aptasia... can get rid of with peppermint shrimp, (I've heard file fish would also maybe help), or you can supposedly squirting lemon or lime juice in their mouths n kill em * although I would research into that a bit before actually doing it, and last course of action if natural irradiation doesn't work would be the chemical "Aptasia x"

Berghia Nudibranchs do a great job. Pricy but they work.

How do you guys tell an aptasia from something like yellow polyp corals? Not going to lie... those look an awwwwwful lot like yellow pollyps. Not contradicting, just curious

[coryhupfer]

Its aptasia I looked into it and thats what it looks like to me. One question though @JOELA7 willl my small frogfish eat these berghia nudibranchs I dont wana spend abunch of money on some and have them get eaten.
