Slow Escalation of Salinity?

[KCK]

Can any fish be slowly exposed to salt levels until saltwater?
Or only brackish fish?

As in;
Could I take a green terror, and throughout a couple years, ramp him up to saltwater, and put him in a saltwater tank?

Or would he just roll over halfway?

You'd kill him; the water molecules in the fish would pass through the cell membranes and into the water.

Keep freshwater fish in freshwater.

It might work for a little while if you did it that slowly, but it would basically be a life of torture for the fish. Imagine feeling like someone is choking you for 2 years straight. And since it wouldn't reproduce, there would be no real point in it unless you are just interested in torturing fish. Jeffrey Dahmer once thought as you do...

In middle school there was a girl who's hypothesis for her science project was that if a goldfish can survive in a toilet bowl, it will survive in saltwater.

Next year she performed a test to determine if temperature had any effect on ant activity; with a microwave.

She won something for both of those science projects. A testament to the intelligence of those science teachers, who saw nothing wrong with wringing out a fish and then dropping a nuclear bomb on some ants.

Not sure I get that.. Are you saying if you drop a freshwater fish in saltwater, all of the water will be sucked out of it and leave it as a dried husk floating in the tank?

Ants in a microwave are fun.. Like pop-corn.. Sad to see a school encouraging that though.

A drop probably not, but no I am not talking about a drop. I am talking about an aquarium full of salt water. Placing a freshwater fish in a marine setup will cause the water in the fish's system to begin diffusing into the environment.


Oops
My mistake I misread your statement.- I dont know if it would totally dry out as I have never had the desire to try this out, but it will die from the loss of water

If you fart a little bit each day in an air-tight room for two years, will you eventually be able to survive on farts?

Just looked it up. I've learned my new thing for the day. I didn't know about Diffusion taking place. But with an extremely slow acclimation, especially over the span of a couple years, it would probably be possible. Wouldn't have the sudden weight drop from losing water, and it gives the fish's slime coat time to adjust.

It would still be torture for the fish though, especially when you start moving past brakish salinity.

Humans need oxygen, so no. If you walk into a pure methane environment, you would die in short order.
