When I was in Costa Rica I saw these fish trapped in a little puddle in the rocks on the shore at low-tide. Fresh water from the rain forest was steadily running into the puddle at a very good rate -the puddle must have been more fresh than salt. A little later the tide comes in washes over the puddle and the fish swim back into the sea.
Last night I bring home a yellow clown goby and test the salinity of the water in the bag -its 1.014 SG! Isn't that low? I took 7 hours to acclimate it to 1.020. My understanding is that inverts are more sensitive to salinity changes than fish.
How sensitive are fish to salinity changes?
Does it depend on the species?
Was 7 hours too long to acclimate a fish given the above difference?
