Any ideas on what this may be? The photo is probably not the best but if it helps it has a green outer ring, very bright when under the blue LED's. The centre is brown. When it closes it folds in on itself just revealing a green outer body. The tenticles are brown. This sits down flat on the rock and is approx 1/2" in diamter.

you have aiptasia. A type of anemone that will spread if you don't do anything. I used Joe's Juice. Works great. Nothing to be startled about, but take care of it when you get the chance.

I have had some aiptaisa in the tank but I added two peppermints and they soon sorted that problem out. This looks different to all the other aiptaisa I had in the tank. The shrimps havent touched it but it is a lot larger than the one's that have gone. Would that explain the difference in appearance?

I thought it looked similar to a button coral (hoping really) or maybe majano but I didnt want to influence anyones ideas.

Cheers

Dan.

Don't kill it yet! It might be an anemone that actually likes living in your tank - which would be a cool thing to have!

Mrktplayer says "That's Aiptasia! Kill it!" to everybody.

Another point is this thing lights up green under by blue light. Does aiptaisa do this? None of the others in my tank did.

maybe majano? That's what I had. I didn't know what it was but I left it because it looked pretty. After I found out it was majano I had it removed. It looked like your picture above, but green with red tips.

Looks like a fully grown aiptasia to me...

Not an aiptasia. Might be in Anemonia genus like majanos. Up to you but I'd leave it be for now.

So the jury is still out on this one. I fed it some brine shrimp earlier to see what would happed. It quite happily swallowed it up revealing a bright green outer body. Does this help with the ID.

Aiptasia

thats a good read on aiptasia. I still think it's aiptasia tho

I think it's a fully grown aiptasia. Most people base their perception of what is an aiptasia on the smaller version. Not a majano.

Uh, it has no 'trunk' - how do you call that Aiptasia?

its hidden in the crevice

What is so bad about aiptasia? I don't have any, but what's the deal with those bastards?

Aiptasia

the link i posted gives info on it. They basically kill all corals as they take over the tank. That is if unattended.

 

[SnowManSnow]

that's a majano

I'd agree... probably a majano. The tentacles are wrong for an aiptasia. I'd kill it quickly (which isn't easy).

Just as an aside, almost never do you find beneficial anemones on live rock. They just don't make the dry transit.

 

[DanH]

I agree that it's not aiptaisa, I have had these in my tank and this is completely different. From all the majano pictures I have looked at they appear to have bulbous (is that even a word?) tenticles?

The anemone does have a trunk but it's much wider than Aiptaisa. Its also bright green in color. I'll try and take a better photo and post this soon.

 

[SnowManSnow]

ummm its a majano

 

[wade1]

Bubbled tips in majano vary by species as well as environmental conditions. The same exists for bubble tip anemones (E. quadricolor). They typically start out dense and bubble-tipped when smaller, and as they get larger they tend to extend the tentacles further and without the bubbles. It could also be related to food availability.

I've seen 2-3 very distinctly different looking majano type anemones (not including their red cousins)... probably sub-species. All of them begin spreading quickly and are very difficult to kill once established.
