hi guys! This is "Something Fishy" (cute, huh!?? my new boyfriend says I'm really creative

anyway, my lifemate Adam and I just got on here and we talked with one of our friends who has both fresh water and salt water fish in one tank, and he says he did it like this:
1) Get 2 tanks.
2) start with the freshwater fish in 1 tank, and the saltwater fish in the other
3) every so slowly, only 1 part in 100 each day, start adding fresh to salt and salt to fresh
4) Based on evolution, both kids of fish will slowly adapt
5) This will take 50 days to reach "saltquilibrium" as he has termed it
6) with your 50/50 mixture, add both kinds of fish into one tank
Hard to believe, and I suggest you try it yourself, but this works. I was there yesterday and will be back later this week and can provide pictures.
I <3 you guys! thanks for the help!
