HYDRA!?!? Please Help!!

[KCK]

I have a 5g tank where I'm raising catfish fry, I'm very worried I have hydra.
I've noticed them in my 45g, 30g, and especially my 5g.
But all the pictures I've seen of hydras look different.
These look like elongated anenomies(Somebody Spellcheck me)
They don't have little hydras budding off of the sides, and they don't have the "chickenfeet" looking attachment.
Are these hydras? The biggest one I saw was maybe 2mm.

Why do people view these threads if they can't help at all?
I really would like to know whether or not my catfish will live

Please help somebody, if this were your problem you would be pretty headless-chicken right about now.

Calm down. Take a picture of it or be patient, thats how the world goes. Nobody wants to guess what a bug is without a picture, from your description it could be hair algae for all anybody knows.

It is rooted to the acrylic, and they swing loosely in the current.
They have several hydra-looking antenna,
Thanks for helping.
Are these dangerous for fry?

I think it kind of looks like this, and this says its a hydra.
But I don't see the egg sacks on any of them yet.

Those might very well be Hydra, and depending on the size of the fry, they may eat them. Two methods of eradication is heat or pond snails. Of course when you heat it up, remove the fry and biological filtration. Heat quickly to at least 106. Let it get back to the temp it was at and return the filter and fry. I have not tried either method, but the pond snails supposedly eat them and should be removed once gone.

Yeah, the little guys in your pic are hydra. I don't have experience eliminating them, only feeding and caring for them. I would opt for manual removal of all visible adults three times a day. Other than that, things that would kill hydra are probably the same things that would kill fish fry.

*I like the heating idea!

Ok so after some thought here will be my schedule/approach.

I already have a retardedly high population of snails in the 5g, which is probably why the hydras aren't out of control.

I'm going to remove them whenever I see them, by siphoning OUT OF THE TANK.

I remember reading somewhere that hydras have "Cellular Immortality"
I think that's the term.
I know it means that they won't die unless violently physically altered or otherwise killed.

I don't think I can heat the tank up, but it's possible.
Would a saltbath kill hydras?

I'm gonna get some sleep, going to portland tomorrow for a week.
At least I get to see the wet spot haha.

i read somewhere that you can spray small dosages of dog internal worm medicines on them.. something that began with an f.. like fomberoides or something.

I wouldn't recomend doing it until you foudn that page though

Hydra can appear in any tank, often appear in conjunction with planaria. Over feeding and a lack of water changes is the main reason. Reduce your feedings right down and up the water changes. With clean water and no food source, they will disappear as quick as they come.
