What...ARE these?

They look to me like they'd be at least as interesting as the fish. Quit worrying about it and get up close to the tank and watch them. Or mail me some :) I think I would enjoy those.
 
Ahh so these things are hydras..I caught a glimpse of a few in my tank. Thought it was algae...
 
how do I get some? lol

I wanna make a 2.5g hydra tank now.. they are really cool looking
 
They creep me out...
There's a little parade of them by my heater on my ten, and they loosely coat the filter head on my five. They've been in the five for ages, and I really don't think it's hydra for that reason, since for a long time the five had no fish in it; only plants and snails.
 
Augh! I just remembered!
I made a topic over a year ago about small carnivorous plants that I had incidentally introduced into my tank! I cannot for the life of me remember what they were called, but whatever these things are, that's what the plants were. They grew from long thin vines and fed on microscopic organisms and very small fry...
That's gotta be what these are, because they look exactly the same.
....Or maybe I have both. Ugh!
Edit: Let me make it clear as to why I'm skeptical to believe this is hydra:
Every picture I've seen marks hydra as splitting from the stalk. These guys sprout as one head on one stalk and have showed no signs of ever separating from the stalk.
The tentacle things are much shorter than any picture of seen of hydra.
They don't have a crown of tentacles on top of the head, they have a smattering of tentacles all over the head.
From what I've seen, hydra grow independent of each other. This stuff grows out of a long vine. I don't know what the stuff in the ten is, but the growth in the five looks exactly the same as the stuff in the 40, and it all originates from a vine.
Sooo....there?

Do you mean bladderwort?

I don't have much experience with them, but I don't think they have threads on them like that or attach themselves onto other plants.
 
I had some hydra in one of my tanks a little while ago but it seems as if they all just disappeared once I cut the feedings back drastically.From what I heard they can sting fish but are really only a threat to small fry etc.Mine hitchhiked in on some new plants i put in tank this is what mine looked like similar to yours but slightly different

I have stuff that looks just like this, but green. They're on my plants and glass.
All I have is snails in the tank.
But I was planing on using alot of these plants on a 55g thats switching to plants.

Is the only way to get rid of them, is to starve everything(all of the snails) in the tank? Or will something(fish) eat them?

Also. What about shrimp? I've been looking fwd to some cherries.
 
Just slowly cut down your feedings until they are gone
