I'm about 6 weeks into a new 6 gallon tank, cycling with 2 danios and
several live plants. I just noticed several very small HYDRA in the
tank. They are attached to, and appear to be limited to, the small
resin ornament in the tank. Can I remove the ornament and boil it, or
maybe submerse it in something (a hydrogen perioxide solution maybe?)to
kill the HYDRA, and then safely put the ornament back into the tank?
Thanks for the help!

This is not meant to be an insulting reply, but does anyone have an idea
why you'd want to get rid of them? I'd think the more co-evolved
organisms you could add to the ecosystem, the better off (complete) it
would be.
