Hello there, we need help! We've got a community tank with baby discus (i know, that is not ideal but we manage to have a good batch, look at the photo!) and we realized that we are infested with Hydra!

The fry is 3 weeks old so not that small, but we want to know if the hydras can be dangerous and if any cure (planaria zero, z-1...) can be harmful to them. We remove it manually every other daybut there's still a fair amount of this freaking thing...

Thx in advance!
