Hydra – Not a good sign??

IMO,... If Hydra develops in your tank, you are doing something extremely wrong.... It's been many years since I've seen any, but thinking back, when I had it, it was regular.... In my experimental days where I still believed in order to breed successfully, your tanks have to be dirty (matured)..... (to build up infusoria)

My views have changed since those days, and I have not seen Hydra since.... Is Hydra really a bad sign, or could it happen to anyone??

 

i think it happens to every one at some piont,
I had it in two of my tanks due to over feeding or so I think any way.
the best way to get rid of it is to add Guppies or mollies and even corries. they sorted out the hydra in not time.
