Hydra?

[skewlboy]

I've see freshwater Hydra before - small (3-4 mm) tiny stalk w/ puff on end and think I see one in the tank - don't look like aiptasia to me but donno. Any idea on what it is and what would eat it?

Can you post a photo of it? There are some things in marine tanks that look similar to hydra but aren't. They are a type of foramina.
