Hi everyone,
Since a few weeks I started feeding shripms (krill superba, krill pacifica), mussels and mysis more often. Could it be that the salinity of these foods negatively affects the health of my fishes?

I don't think so.

you still "rinse" the food with water under a running faucet in a fine net like you used to? then the salinity that gets a hike along is minute.

I wouldn't worry, everytime you do a waterchange it is more than just cancelled out.

think about this: we all feed frozen artemia (or at least many of us do) and that stuff is bred in water maybe 3 times as salty as seawater. no fish gets harmed when it gets raised or fed on artemia.....

Unless artificially salted, my understanding is that most animal life maintains it's internal balance of electrolytes at roughly the same concentration whether it is of marine or freshwater origin.

Yup, that's why sushi without soy sauce isn't salty.
