aarg those hydra's

[Erik82]

Hi all,
the breeders under you probably have had some issues with hydra's. Well those teeny little creatures are in all my tanks not very much but enough to bring down the amount of fry.... Mostly they come with the artemia witch i use to feed the fry.

Since a few weeks my A. sp blutkehl are very reproductive. As all breeders i would like to grow the fry up as much as i can. But i noticed that the hydra's eat some of them.

I would like to get rid of them but how? I heard about using a battery (example: http://www.hamco.nl/files/image/products/Batterij_Varta_9V_Blok_418x325.jpg) by using a copper wire at the plus and min and put this into the water. But will this harm the fry? Which method do you use to get rid of the hydra without harming the fry or snails?

Best regards,
Erik

Your post got me thinking. I have this in my main tank. They are very tiny and accumulate on the glass.

I found this link.

And am trying the remedy right now.

Hydra are not something ive ever had a problem with.. Several friends do have problems with them though.

One uses the battery method and actually touches the hydra with the copper wire, this zaps them and kills them off..

The second uses apple snails and explained to me that they are very effective at clearing them, this fishroom is actually a public aquarium and i was in the breeding room behind the scenes, these fellas know their stuff and can be relied on for accurate information and tips..

Hydra treatment

FLUbendazole (a chicken de-wormer) kills Hydra in a few days, and is also pretty effective against many ectoparasites (including ich and velvet) and some intestinal protozoa and worms. It is safe even with very young fry and doesn't seem to bother filter bacteria. Charles Harrison in Missouri USA has info on Flubendazole chemistry and use here:

Thanks all for thinking with me. It is to late for the A. sp. blutkehl. All the fry has gone into the little ugly creatures :-(

So 4 days later and I still have what I think is hydra. The safe guard that I got has fenbendazole not flubendazole. Where can we get that?

Spixi

Spixi snails eat hydra . I had hydra in my 40 gallon so I put 5 spixi snails and iv not seen any hydra so I think the wiped them out ! Mind you they also wiped outy dwarf Jair grass and sent all my water sprite lose but chewing the stems .... So if it's a planted tank maybe stay away from these guys lol

At the advise of a senior breeder i tried some substances. The thing i used is Gatstropex. Officially it is a pesticide for against snails. It also is very effective against hydra's! All of them are gone now!
