anyone know what this is?

it started as one xenia-type but now has pups all over my tank.

 

aiptasia=pest! use joes juice or similar product

 

looks like an aptaisa!!!! not good nuke that sucker...might wanna get some aptasia x...or try injecting it with boiling h2o or lemon juice???

 

thanks JM - was going to leave it but now it's taking over all over the place

 

Cant see the base but it is probably aptasia and you need to kill them all if they are spreading. sooner the better....

You can use aptaisia X or i use kalkwasser.

Wait for a few other second opinions though just to make sure. It always a good idea to get a second opinion;D According to my wife, im wrong quite a bit

 

joes juice em

 

....Wow everyone responded to that fast. I think you are safe Kill it

 

thanks everyone! didn't know it was a nuisance but i'll get rid of it

 

I use kalk paste. Nuke it.

 

You've got alot of them!
