What are these?

[wakerider113]

If anyone knows what these are, please help. They look like aptasia (and reproduce like them) but they have bubble tips as opposed the traditional aptasia that i am used to. Are they just a different type of aptasia? Im running a small 14G biocube and they seem to have taken over quite rapidly and ive been too busy to deal with them.

Thanks
Mark

Majano anemones (pests).

better deal with them or you'll have a tank of them. I inject them with vinegar.

well theres about 200+.. anything i can dose the tank with that is fish friendly that will stabilize them at the least?
