its very very possible just slow
so far converted mangrove jack/toad fish/catfish/bream/ few other things
secreat is mate do it very very very slowly or u will stress teh fish / cuase them alot of pain
but from my experiance if done right and not rushed but impatiants u can do it with out cuaseing much pain if any to the fish also u will have a 90% success rate instead of 30 70
u need to recreate a estuary like enviroment eg. the bucket of salt water where u court the fish or a bucket of salt water from a upper estuary river
ok now what u want to to is simulate as if it has rain very hard for a few days = lessen the salt concentration
so bacicly what im telling you to do is 20 ltr bucket of salt water 2 huge air pumps a brackish water fish one time a week remove 1 cup of salt water and replace it with fresh treated water dont remove the cup all at once u need to like drip it out over time of the week and same to replace it with the fresh
this can take up to 3 months if done correct and not rushed
ok next this is dont try to do it to any fish over 5inch if teh fish is any larger expect a fail/death rate of 75% to 85% the younger the fish the betetr and so much easyer for them to adapt
ok next thing
yes this will reduce the fish's life span is most case's except a select few fish
but my point of this post is that IT CAN BE DONE
just dont be a idiot and try fish that just wont work and be very patiant
