"anenome"-ish grwth appeared in my tank - what is it?

[Dude64]

I have a 40gal reef with 4 Molly, 3 crab, and a variety of snail in my 1 yr old established tank. This guy (close up on right) and a few friends seem to have appeared from nowhere (snail hitchhiker I presume), but I haven't a clue what it actually is. I have never had (bought) anenome in this tank. He is about 3/8-1/2" tall atm.

Aiptasia

Definitely aiptasia. If you can remove the rock, scrub or superglue that guy out of there.

Aiptasia anemone. They’re a pest in the reefing community because they are unsightly, spread extremely fast, and can sting neighboring corals.

Aiptasia-x will help you get rid of them.

I have some in my tank. I like them though. as long as they dont get out of hand I consider them just part of the community.

I turn off all flow/pumps and then just squirt some H2O2 or lemon juice directly into their mouth. Let that dissolve them for a couple minutes, then do it again to get their foot that is buried in the hole. If you leave anything behind, they will regrow after a few weeks. H2O2 and lemon juice are cheap and I always have some on hand. They do a good enough job that I've never felt the need to buy any overpriced aiptasia specific products.

I don’t have any in my new tank but I agree I liked them in my old one they’re kinda cool looking and they’re the only anemone I can keep alive lol

Mix some kalk into a paste and cover it . I have found it to be the easiest way to irradiate them

Aspasia anenome, very bad and spreads fast. Try to get rid of it as soon as possible before it spreads, there are lots of different strategies to getting rid of them, my favourite being:

Put boiling water into an eye dropper or syringe, then spray it on the anenome. The anenome should retract into its hole, after that smother glue over the hole, this works well.

If you really hate them that chemical apista x or whatever kills then in a sec …I’d only use it on the ones that close to my real corals bc man do those little buggers have some sting

Thanks all replies... Aiptasia pretty sure, but I (so far) control them simply by spot treating with Boiling RO... I keep the one and even tried feeding him while feeding hammer... granted the two swimming buddies are at extreme opposite sides of tank.
