WHAT IS THIS

It could also be one of those walking (swiming) anenomes or a curly cue anenome.

I have plenty of majanos in my aquarium and when they are young the majanos look like zoos then later develop bulbous tips. I kind of like the majanos because they look nice and don't reporduce super fast (I know they are bad though).

Could it be a tulip anemone? Mine glow like that and can move pretty fast when they want to go somewhere.
