Hydra. These are a threat to small fry. High heat over 24-48 hours will kill them....

I had some introduced years ago while breeding angels and I lost a bunch of fry before I realized what had happened.

Thank you much!

Hi,

Unless you are breeding things, the Hydras aren’t doing anything but cleaning up.



Times are tough; all they are doing is seeking gainful employment.



They are also fascinating little critters.
