Hi there I was wondering how bad and how hard an infection of hydra can be to get rid of ... I have a 40g planted tank with about 35g of water, I have mystery snails, rabbit, and nerite snails, and I’m trying to grow out a about 30-40 ghost shrimp.. I’ve done some research saying use chemical in a tank but most will kill the snail and shrimp, I tried putting guppies in about 12 to see if it would help, I just don’t know anything about Hydra. Can someone help?
