Hi,
six weeks ago I found in the backyard of the 20l tank a lot of those green Hydras. Because I keep 4 very young red cherries in the tank I need some more informations about how to get those Hydras complete out of the tank. The temperature method I tried out - without success, the Hydras came back within 2 weeks. Because of the snails, I don´t want to use the flubenol. Is there anything else I can do???

hai michaela,
*g you´re from germany, me too, but I try to write english-
the green hydra has the possibility in photosynthesis --> no food, no problem 
water must be warmed up , to 42 grad/110 fahrenheit, so no chemicals must be used.
sorry, me english is worse  |

Hi Alex 
well lets try it in english  . No food-no problem might be right for the Hydras but I keep Amanos and Red fire Shrimps in the same tank. At the moment I feed the shrimps with spirulina tabs, because the Hydras love frosted foods, also baby shrimps but no plants. Two weeks ago I headed the tank up to 42grad/110 FH for 3 hours. The Hydras did not survive but I guess the eggs of them. Right now they are back and sticking everywhere. I don´t know how the shrimps react, if I keep them again for a day in a bucket just to heat the tank up. Got some idears????

Hi Alex,
I have some babies of the Lymnaea stagnalis. Hope they are hungry enough to find all of them. I keep also Planorbarius corneus, Melanoides tubercutata and Physella acuta togeter with the Lymnea stagnalis, in the same tank. Right now - with all the snails, shrimps and half foodrations should be nothing left to keep the Hydras alive.

I used red ramshorn snails to get rid of the hydra I had in my shrimp tank.
Another method is to take a small medicine dropper of hydrogen peroxide (H2O2, 3%), squirt it on the hydra, then immedietly remove the hydra with a pippette or syringe without a needle. Of course, if you only have a few, this is possible. The hydrogen peroxide is safe for shrimp and snails in small quantities. You can do a water change after, but it's not really necessary. |

Hello lotus,
I think I´m going to use the hydrogen peroxid. I heard about it last week in our pet store. Do you know how much ml of the hydrogen peroxid I can use in a 20l tank. I would appreciate your answer, cause the hydras are sticking everywhere right now.

| I would get about 5-10 hydra at a time in an approx. 40 liter tank, so I was using about 10ml of 3% hydrogen peroxide at a time, followed by a small water change as a precaution. I'm pretty sure you could use more than that without a problem, I just wanted to be safe. |

Hi lotus,
well your answer came a little bit to late. I used the H˛O˛like as they suscribed on www.zbbf.de - 15ml for about 4 days. The shrimps and the snails are still doing fine, the hydras disapeared and all my plants too. The whole tank was in a big mess. By now I changed a bit the 200l tank and the shrimps are swiming big circles to find each other
For the next time I know how to use this stuff.

Hi there,
I had problems with Hydra once, transfer all the shrimps to another tank and introduce Pearl Gourami to eat up all the Hydra. Hydras killed about 30% of my Crystal Red Shrimps!
Take note when transfer shrimps to another tank. Do not transfer the Hydra infected water to the new tank. Put the shrimps in a small container and acclimatize slowly with the new tank water before introducing the shrimps without water into the new tank.
Regards,
Emorsso |

Hi,
in Germany some people have been experimenting with Panacur (Fenbendazole). It works well against planaria without killing the snails and also against hydra. Takes longer, however, than Flubenole, but that has the great disadvantage of being a snail-killer.
Cheers

| Im pretty sure other fish like guppies and mollies will eat hydras as well. Transfer the shrimp out and put some mollies in for a week or so. |
