Alright, this is what my mystery anenomes look like. Rust color (very small, like 1/5 inch I would guess), the base of the tentacles are white, and the tips of the tentacles are green, in between the base and tips are the rust.
I just want to know if they are aptasia because I am finding more and more every day. And I have heard that aptasia is bad, but what is so bad about them? And what is a good/easy way of getting rid of them?
Please let me know, I don't want a tank full of these critters if they are bad!
