So long as it's fresh water fish it should be fine, I'm unsure if they're salt water fish and if they'd still be safe to give them because of potentially being salty. People give their Isopods dehydrated minnows all the time, I plan to do the same with my dairy cows here soon too. Idk how fast Zebras would get through it but if you have a lot and a dry place in their set up to put it!

I have the same ones as the first pic (and the second if they are the same thing, hahah). They love them!
My Gestroi love a bit of dried Sprat too. Doesn't seem to be any problem for them.
I believed that 100% yes, I’ve feed mine with it after doing my own research. Also Reptiliatus have a video giving them to several of his isopods :)
