Little brown jellyfish

[cartoonbear]

Are they good/ bad? I just noticed them popping up. I think at the present moment I've spotted about 5 at one time. Should I worry about them or just let them be?

Pictures?

I wont be able to get ne til later and I doubt they will come out too well.

Do they resemble aiptasia, but can move around the tank swimming like jellyfish? Brown coloration, when opened looks like a zooanthid? If it's what I'm thinking, (can't remember the name) they can multiply quickly, but a pic would help.

sounds like ya hit it on the nose, but I will try and get a pick later. Will they become a problem?

 

[macronut]

I had some and siphoned them out. I can't remember the name for them. Bad thing is they can swim and land wherever they want.

If it's what I'm thinking, they can become a plague like most pests.
