Turning Saltwater Fish into Freshwater!

[Lord Gaz]

Okay, Im sure outta the thousands of people here, at least ONE of you have done this before! The idea is to turn salt water fish into fresh water fish. I really want to try this because there's so many cool salt water fish that I can catch, but I cant be stuffed to maintain a salt water tank because it SEEMS like too much trouble to set up. My friends' cousin is currently doing it, and apparently he said that some the fish in there is about 80% converted.

Now, the question is: how do you do it? How long does it take for this process to take effect? Any recommendations how to set up a tank?

I've always wanted to keep an eel (or two), so if this theory really works I have to test it out!

i hope your theory doesn't kills your fish, it is possible you can convert a salt water moray eel to a brackish moray eel you tank a little bit of salt out of you tank every month(go down to every point on the sea tester once a month and until it reads 1.000) but i don't recomend full fresh water at all.

that is what i was told by a man who came in a bought 3dozen goldfishes for his 8ft moray eel.(they are my favorite eels even over the peackok eel.)

dont bother

even if you manage to do it

they wont live very long and will die from complications

i tried it, i had a salt water perch with a white spot on its body. converted it to slight brakish. then after a few weeks of surviving the brakish i brought it down slowly til it was pure fresh. seemed ok for the first few days then poof. he was dead.

Don't do it! All your doing is slowly killing your fish. If there were cheap ways to keep marine fish like that then everyone would be doing it. It's a very, very, very, bad idea. You will kill all your fish. This is why there are Marine tanks, brackish tanks, and fresh tanks.

get a saltwater tank, or dont do it. The fish will die much sooner than they would if they were kept in their conditions. Very stupid idea

 

[dannyboy]

it only works for some species of fish, but i doubt the fish you would do it to would survive.

Fish like barramundi and salmon, migrate from fresh water to salt water.

im guessing if you do it the will die (unless they naturally migrate from salt water to fresh water)

Common Sense says Don't Do It!! It's not natural and will only stress an already stressed fish. Call me what you will but I believe this to be downright stupid! JMO

Not a good idea. Some saltwater fish will convert to brackish, and rarley, even to fresh, but this only works for esturine species, such as flat head, mangrove jack, estuary cod and some species of gar. Of all these, only the mangrove jack would survive full fresh water, but even then, would probably not do so well. The main reason saltwater fish cant live in fresh water is all to do with the structure of their cell walls, and the way this effects osmosis. I'm not sure of the exact details, but it basically means that a salt water fish in fresh water will die slowly and painfully.
