Hydras Found In Freshwater Nursery Tank!

[Sollo]

Have never seen this yet a friend called about Hydras in his freshwater nursery tank. These things don't look to good - any ideas?

He also has a fairly large in ground pond that is just over a year old.

The fact they are in his nursery seems to be a problem as they will or may eat the young from what I read online.

Does he need to attack this - if so how?

Thanks!

free food for fish....

yup- they'll disappear soon. I've had em and they present no issues- just entertainment.

not enough current plus too much food equals hydras in my experience

Thanks for the replies - will pass this along. We do have a very small blower that might help him in his tank as well.

Hydras can be detrimental to baby shrimp, otherwise they are free fish food, and also come from overfeeding or lots of rotting leaf litter.

If you want to kill them use Aquarisol. It's cheap and works quickly like salt on slugs.
