What is this?

[EdsonFOWLR]

Just added three new pieces of live rock to my new tank and noticed a few hitchhikers. I noticed a very small black and white striped starfish, and what looks like a coral of some type. If anyone know's what these are it would be greatly appreciated.

I would say that's a Manjo Anemone. It's a pest anemone that if left unchecked will take over your tank and make your hair fall out (from stress).

I would wait for verification from another person and then commence the war.

Why are the Manjo Anemone such a problem?, would it even be a problem in a FOWLR tank?

Aiptasia. Majano's aren't as translucent. They also have clubs at the end of their tentacles :)

They can reach plague proportions.

Yes and no. Depends on what you think of their looks. Also depends on if you get a "creeping death" strain or a "rabbits of doom" strain.

But these are Aiptasia, so you probably want to get rid of them regardless. They look like stringy algae when they get going hard. Not very nice at all.

Looks to be aptaisia anemone.

couple of options to get rid of them...
1. Slush mixture of sea salt applied directly onto anemone via baster.
2. Aptaisai X chemical remover.
3. a squirt of boiling water on the site.
4. Peppermint shrimp (hit or miss)
5. Certain fish eat it
6. bergia nudibranch
7. cruise missile

the last one might cause a sandstorm...

+1 for aptasia. Aptasia X works good and doesn't release tons of spores all over ur tank.

[pinkreef]

get aptasia x it comes with a syringe and a couple of different heads
it is easy to use and will get rid of the 3 i see. you have to sneak up on them or they will scoot into the rock. :biggrin:

[Misses.ReefWars]

slighly quicker way is sufficate it with coral glue or apoxy :)

[monza]

Personally I'd take the rock out and dig /smash around the aptaisia area completely removing it and any signs of it from the rock. Actually though, if it was me I would not even use the rock, it's a plague that may take years to get a foot hold but if it ever does you'll under stand. I see a few in your picture which means they can and probable are hiding every where in the rock.

I use lemon juice in a syringe. The insulin syringes from a pharmacy work well. I haven't had one since my tank first started up.

Also depends on if you get a "creeping death" strain or a "rabbits of doom" strain.

Do you have links to pictures of these strains of anemones? You have piqued my curiosity.

LOL, they all look the same. It was just a joke regarding the rate that they spread. Sometimes they're fast, sometimes they're slow.

Cheapest and easiest.....go to Canadian Tire, head to paint department and buy a 9 dollar bottle of Muriatic Acid. The stuff works awesome.

if you're looking for fish suggestions for your FOWLR, could consider a tile fish. Not that big, little strange looking, follow you around the tank plus eat aptasia.

You have a scientific name for the tilefish?

[reefmandan]

I wouldn't try to dig or cut it. Any small part/fragment (especially the foot) can grow into a whole new anemone. I use a kalkwasser paste and inject it directly into the anemone with a hypodermic (insulin) needle. Works everytime, and works great!

meant filefish (http://www.liveaquaria.com/product/prod_display.cfm?c=15+30+2562&pcatid=2562), Acreichthys tomentosus

+1 for lemon juice in a syringe, sometime I even microwave it for a bit so it's nice and hot for those little buggers
