hello my dudes and dudedettes,
I'm from Indonesia and many people from my country have successfully converted saltwater fishes into freshwater. I believe they acclimate them slowly with saltwater by dripping freshwater into their tanks, the process takes between 1 week to 3 months and I've even seen a marbled catshark being acclimated. Honestly, this is pretty cruel and unhealthy for the fish even though some of them live for a very long time, it is like putting a human being in a small room and breathing in only smoke, they will live but they are suffering and won't last as long as they should. If you guys are interested in seeing pictures of the fishes, pm me or email me: rafanuel0929@gmail (i cant post a link or a file since i just signed up)
