This has had some(somewhat "highjacked") discussion going on over here >>> http://www.aquariacentral.com/forums/showthread.php?t=186479.

I'm looking around reading and trying to find a way to deal with these in My tank. So I thought I'd start my own thread, for here out.

My tank right now...

What I've got from reading here and there so far.

Hyrda, basically are going to eat anything small and alive. Which seems to include all these lil snails.

Ways to get rid of them that I've found.
formaldehyde.
This isn't much of an option in my eyes. Athough I read an article about accomplising it with fish and snails in the tank. I'd worry about the future of having shrimp.

Temp - 110 degrees for 5 minutes.
I don't see me removing all the sanils for this to happen.

Possibley...

Loaches - I didn't read much on these. And what I did read was on a forum, and they weren't being specific about any. Deffinately won't be putting a Clown in there. He'd eat all the snails before worrying about eating a hydra.

Mollies - Some say do, some say didn't.
Gourami - Some say do, some say didn't.

=======================================================

Anyone have anything else to add to the list?
 
I'm pretty sure that hydra only eat microscopic organisms within the tank, I'm not too sure they'd eat your snails.

Reduce the food fed to the snails
By that, you reduce the food that gets to the microorganisms
Which decreases their numbers due to hunting by the hydra
Then the decreased numbers of little guys leads to the death of hydra

No more hydra = happy you :]



Also, gravel vac a lot more.
 
How many Hydra do you have? You could just suction them out with a turkey baster.

From what I've read they will eat anything small, including water fleas and small fish. And I have to presume, this means snails too.

Here's a link with the reference to water fleas, and newly hatched fish.

I do have fleas, too.

And like I mentioned in one of my other post. I'm thinking the starving the snails won't work...

Food reduction -
Sense the Hyrda are probably feeding on my lil snails. I can help but foresee the senario of...
Starving the snails to death and the Hydra would be the last one standing.

I haven't been feeding a whole lot really. Maybe the equivelent of an algae waffer a day. And now that there are hundreds of snails. What is feed is gone in no time.

Gravel Vac - I haven't actually done this yet.
The tank was set-up specifically to grow snails for my brothers, dwarf puffers. And having a hard time getting any hitch hikers on plants. (I thought that was going to be easy). I have alot of plants and started with only a couple(literally) snails. So any cleaning was not going to happen.
Although with finally having a good snail population, so I can clean however much I want. I still have to deal with the hydra removal. And the less feeding doesn't even seem like an option. Because of the screwed up senario of the hydra eating the snails. And being the last thing standing.
