clear jelly things floating around

Have seen these a few times, I think they either anchor some place behind a rock or get drawn into the overflow box. Any ideas? Could they be jelly fish?

 

I think it is the remains of a green bubble algae.

 

I'd be pretty surprised since I don't have any bubble algae. Also some of them have been opened, sort of looking like a polyp of some kind.

 

that was my thought too... but I'm not sure.

Next time I see one, I'll catch it and take up close pictures.

 

I would say Hydroid jellyfish, but it's really hard to tell from the pics. They look more like smooth bubbles in the pics.

Do they look like this close up?

sushigirl, that is pretty close to what they look like. I see them once in a while. I also saw one in the mouth of a mushroom.

 

Probably jellyfish then!

 

Looks like the "clearish" bubble algae that I see sometimes floating around my tank.
