Got rid of mine with dwarf gouramis. Not sure how useful that is to you. £3 for a gourami though.

"Panacur" (Fenbendazole) works and is pretty non-toxic, you can buy it as granules via ebay, as well as as a 10% solution.

There are details here <"Hydra removal">. The Panacur isn't instantly soluble, but all the bigger fragments will eventually go into solution. I roughly crushed them up with a pestle and mortar, put you could use a rolling pin with the granules in a plastic bag.

Rather than trying weigh out 0.1g in 10 gallon (~50 litre), if you buy the 1 g sachets, pour the sachet out and divide it into five equal portions by eye. Each portion will then treat 100 litres of water.

cheers Darrel

Hi all,

hat is excellent instructions man thanks very much, ill give it a go

I got the amounts from <"PlanetInvert: Killing Planaria and Hydra....">.

I think Hydra are a lot more common in aquariums than most people realise. Some of my tanks have run for a long time without any fish, and apparently without any Hydra, I've added fish (either for quarantine or fry to grow out) and started feeding live food (Daphnia, Grindal worms, Micro worms) and the Hydra have miraculously appeared. I don't think they've come in with the Daphnia, so there must have been some present, just ticking over, until the live food bonanza arrived and kicked them into reproductive mode.

I've often had the green <"Hydra viridissima">, which can survive the lean periods by living off its algal symbionts, but I've had non-photosynthetic ones as well.
