Is this some type of Nem?

I found this living on the lower part of a rock in a low lit portion of my tank. I haven't added anything new in about 4 months so idk where it came from. I am wondering if it is an aptasia or something. It looks like it has green and white tips under blue light but seems clear under whites. Thanks for the help!

It's a corallimorph of some kind from the genus corynactis. It sort of depends on where they're from though. "Strawberry anemones" and "Jewel anemones" are usually colonial temperate species if I understand it correctly, though there are very similar tropical Caribbean species as well - which is probably what you have there.

 

If you want to keep it, they aren't aggressive. It needs to be fed though. Feed it small pieces of meaty food and it should grow to around 1" in diameter. If you don't feed it it will probably die off at some point. Then again I've had them disappear even while feeding them... As for reproduction, I'm trying to remember but I believe I had one that "budded" out clones occasionally, though I don't recall any of them ever doing well.

Florida/Caribbean live rock? If so it might be a cup coral. Hitch hiker related to sun corals and dendro's. Think plain cousin.

Ok cool thanks guys it is for sure a ball anemone of some type. I know the pictures are crappy it is in a hard to photograph spot. It has a green center and blue tips. I feed my corals daily (vodka dosed system) to keep my lps and softies happy in an ULNS so ill just shoot it some food too. Mine is already about an inch in diameter maybe he likes all the food I pump into my system. I have no idea what so ever where it came from because I have not added new live rock for over a year. I upgraded my tank from a 25 to a 45 about six months ago but i only used dry rock from BRS. So strange but very cool! Do they need much light? Mine is pretty shaded so I am assuming the answer is no.

To be honest, they usually die off eventually. when they pop up in my tanks I don't feed them. and yes, they tend to stay in shaded areas. at least mine have.

I've had a couple of ball nems living in my pico tank for a couple of years. They don't seem to bother anything and I don't do anything to directly feed them. I just leave them to their own devices and they just get on with it. :)

Just a nit-pick here, but while these are often referred to as "anemones", they're actually corallimorphs - so more like mushrooms or ricordias than anemones.

 

IMO calling them anemones leads to more confusion and it seems like questions about these guys come up all the time with many people thinking that they're equivalent to aptasia or majano and wanting to get rid of them.

 

I think the only thing needed is to determine if it's a corynactis sp. (pretty sure yours is) or the more aggressive Pseudocorynactis sp.

 

Either way though, not a nem.

How do I tell the difference between these two types?

Didn't know that. Only known them as Ball Nems. You learn something new every day. :)

I did not know this. I have a few of these in my 10 gallon and I had a lot in old 40 gallon. They like to live in shady areas from my experience and also glow slightly green under blue light.

Just do an internet search... There are a few decent explanations that aren't hard to find. It may take some reading but that's a good thing ;)
