Could someone please tell me what this is?

Sorry I know it's a bad photo but it's at the back of my tank so can only take a pic from the top. It kinda looks like it's got tentacles?! Any ideas would be great! Thanks

Is looks like an appy?

Funny I was just searching other threads and saw you had identified a similar looking one as an appy.

Do they do any harm in the tank?

Burn it with fire before it spreads. And it will take over your tank if not killed now. It's a very bad type of anemone hitchhiker. Look up Aiptasia.

Thanks very much! Got him out so hopefully there's no more

 

[domination2580]

If there's one ther is probably eggs. Id inspect all your zoas for eggs

 

[Fishyfingers]

Ah crap ok I'll google to see what they look like and see what I can find. Thanks for your help

Do you keep zoas fishyfingers and if so have you got any sulky ones?
Looks like a zoa nudi to me and if so if you have found one that big you could have a problem that needs treating.

I have recently purchased Zoas and thought it looks a bit sad because the naughty coral beauty was nipping at it what would you suggest to treat the problem? I bought a coral dip but not sure if that will kill any eggs also not sure if I need to dip all the corals or just the zoas? Any suggestions would be appreciated

Every coral should be dipped. I personaly dont with anemones but its hard for a pest to transport on them since they are fleshy. Also coral dip will not kill the eggs. You need to ma ually remove them. Or for many reasons y we have qt is to watch them. You initially kill the nudis but they lay eggs, so you leave them in qt and the instant you see more nudis you can kill them with flatwormexit

Coral beauty could have been after the nudis.
Got any pics?
Not sure what lights you have and if they ramp up and down or not, the nudis take on the colour of the zoas they are on, easier to spot under early morning blue lights.
England here so not sure what you can get for a dip, Coral RX is popular over here, I use Dettol.

Am i correct @lionfishlair?

Yes. Absolutely.

Those things love zoas. They don't always take on the color though. Often you'll find they stay a brown/tan colour.
