What!?!?!?!

This adaptation is called being euryhaline. There are lots of fish that have this ability. You need to go slowly when going from freshwater to saltwater and vice versa because the fish need to change the way they osmoregulate. I work with tilapia (O. mossambicus) and we have kept them in salinities all the way up to 90 ppt or about 3 times saltier than the ocean. Desert pupfish can tolerate up to 120 ppt. Fish are amazing!

dang...3 times more saltier? that would probably burn a fish even if it was from the ocean lol. and indeed fish are amazing

Silver tipped sharks (and many brackish fish) do best when the salinity they are kept at increases with age to the point that the adults are basically in full salt. While they can survive in freshwater, it isn't good for them

many fish can survive in the wrong conditions, with a shortened life spand.

I kept a gold molly in my nano reef for a while but then it jumped after 6 months

A true euryhaline fish will not only survive in fresh and salt water, but they will also reproduce.

Hey Studdmuffin not to derail your thread at all but I saw in another thread that you are going to Santa Barbara soon, just curious if you could recommend a lfs there?
