I dont know if you know this already so please dont take offense.... the julian sprung sea veggies of all kinds are much better for your fish than nori from the supermarket.... if you gave some to your fish and they didnt like it, it is because they are not used to it... you will need to feed almost the whole foil pack untill they will lik it, then they will devour it... much better for them... just a heads up

I have feed it for years with great results
