Thanks! The moss is making a come back lol. I bought it recently and it had hydra on it. I absolutely cannot stand hydra so I did a risky bleach dip. The moss wasn’t happy as you’d expect lol but it’s really turned around from what it was!
We have a few <"Hydra"> threads. As a safer alternative fenbendazole <"Panacur"> is very effective against both Hydra and Planaria.
I used to have a <"Hydra tank">, It had various "growing out fry" and then Trichopsis pumila, and they mainly got micro-worms and Daphnia. Hydra love small live food items, and they multiplied out of control.
