That was posted in the vid section a few weeks ago. But it is very interesting stuff. I would like to see some fragile salt fish in it though. I have read about people keeping clown's in very low brackish conditions with no problems. And most of us use regular salt in our fresh set ups. I think in the years to come we are going to see alot of stuff in the hobby that bends the rules.
10 years ago having a green spot puffer in fresh water was unheard of. Now we have moray eels , puffers, goby's, etc, etc that used to be salt fish in fresh all the time.
I personally don't see a point to this freshwater fish weren't made for saltwater and saltwater fish weren't made for freshwater. It is going against all good aquarium husbandry goal's
