Pegasus Posted June 29, 2005 Report Share Posted June 29, 2005 Didn't know we had Hydra in NZ.. but in answer to your questions.. do i need to worrie about them Yup.. you sure do.. they can attack and kill small fish. can i get rid of them easly? Don't know of an "easy" way.. I think the last lot I had back in the UK came in with some Argulus (sp).. (Water louse).. and I used Potassium permanganate to kill them off.. but OH.. what a mess it made. Someone else may offer a solution other than this drastic measure. Bill.

PENEJANE Posted June 29, 2005 Report Share Posted June 29, 2005 This is what I got off the net to cure it. It was actualy tested by the guy himself. ****Cure: "Add one teaspoonful of vinegar to every two gallons of water in the tank. Concentration may be increased". I started off at the suggested rate amount of white vinegar, one teaspoonful to 2 gallons. The fish appeared to be all right but the Hydra were uncomfortable and retracted into squat blobs of a greyish colour and some fell to the aquarium bottom. Was this chemicial warfare going to be effictive? I increased the strength to double that recommended. I.e. by adding another teaspoonful per gallon, the mixture ratio was noe 1 teaspoonful per 1 gallon. It definitely worked but after a day or so the water went cloudy and requireed a water change for several days until the water clarity was restored. This cure worked in the stronger solution. I now used this solution in tanks 1 -5. Score total victory for me. I wish this story had a happy ending but last week I noticed a few isolated Hydra back in two tanks… you may think you are safe now that the Aliens have been conquered as well as the Body Snatchers also the Creature from The Black Lagoon…. But beware the HYDRA are coming. In fact they might already be in your tanks, hiding.**** I know that it would require a lot of water changes afterwards but if it won't harm the fish then its worth it to get rid of the hydra. Wasn't to sure on how quickly you were seeking a responce so I have been searching since 6.30am lol What....... its not like anyone else is awake at this hour in my house Quote Link to comment Share on other sites More sharing options...
PENEJANE Posted June 29, 2005 Report Share Posted June 29, 2005 Oh and for further reading here is the site that I got this info off. There is also some more info there about livebeares and this problem. Apparently Red Ramshorn snails worked to See Snails are not just a pest Quote Link to comment Share on other sites More sharing options...

Aqua Posted July 2, 2005 Report Share Posted July 2, 2005 I just squooshed the one hydra I discovered in my tank! Boyfriend wasn't so happy about it, as he's studying Marine Biology, and had just studied chlorohydra :lol: Quote Link to comment Share on other sites More sharing options...
Interfecus Posted July 2, 2005 Report Share Posted July 2, 2005 If you find another, let him experiment on it . Apparently if you turn them inside out the cells all start migrating through the body until they're the right way around again . Quote Link to comment Share on other sites More sharing options...
