converting a freshwater fish to saltwater

[Jim96Sc2]

Not an expert but hear me out.


Skipping fish that are brackish water fish or ones that change over their lifetime.

Fresh and salt water fish are two distinctly different animals. Its like throwning Polar Bears into the tropical rain forest, they just aren't suited for it. The excretion/absorbtion processes within fresh v. saltwater are different. Look up the methods each use to maintain homeostasis within their respective enviroments then ask yourself if you think they could change their physiology.

I totally agree, I cant believe this person even asked this question. Lets experiment with him and a bunch of people and see how many survive. How cruel can you get? these are fish, they are living animals that can feel pain, if you could feel what they would go through in saltwater maybe it would teach you not to 'experiment' with a living animal. If only the smily wasnt smiling....

Im in enriched science at my high school and every student is required to complete a science fair project. I was thinking of different way I could do this while doing something interesting using some of my fish tanks. Then I got the idea of trying to convert a freshwater fish to strait salt water. Now I would do this very slowly adding a little bit of salt to the tank every week over a 3 and a half month period until I have converted the fish. Now does anyone think this would work??? If not does anyone have any other ideas that I could do??? What kind of fish should I use (they should probably be fairly tough/sturdy fish, not delicate)??? I was thinking I would like a bigger fish and not mollies/guppies/tetras but these could work, I was thinking of a fish maybe 1-2 inches fully grown. Also I would probably need between 25-??? fish I think so that I would have a higher chance of having some survive the process (they would have to be fairly cheap). What do you guys think???
Cant wait to get started soon!!!

Up to what point do want the salinity level at?????You can get away with it with Mono Sabs or some Mangrove swamper, but I highly doubt a freshy will survive in an average salty water chem...Good luck on the project....

May not be a good Idea but will but it out there.
Get two fish that are carnivores and eat feeders.
Feed one feeders and the other a well balanced diet.
See which one grows faster and has better color. If the one on feeders doesn't die first.
