Bump!
It's a serious question, really!

Hey #reefsquad any thoughts on this?

One final attempt to solicit a response...

Can anyone confirm if it's okay to treat a DT with hermit crabs using Formaldehyde (Formalin) at the recommended concentration of 15-25 ppm? That's 13-ml of 37% Formalin in a 55-gal tank.
I know the fish will be fine, just not sure if hermit crabs tolerate Formalin well?

Anyone... anyone...
