I’m cycling a new tank before moving my shrimp colony over. Pretty early on. I found these on the glass during a water change. Do I have to restart my tank are these guys harmful??

    That’s hydra and it multiplies

    I wouldn’t burn it but maybe empty out the water first if you do

    Hydra, they will eat baby shrimp. Got some fish that you don’t mind starving for a few days?

    Obligatory hail hydra.

    Also, I know there are fish that would happily snack on these!
