anyway they did kill alot of clowns on the day of the exhibition , but probably because they never acclimatise properly , you dont even need magical water if you want to do it, just need to hypo your marine fishes to 1.010 over a 5 day period, and hyper your fresh water fishes , then do the usual acclimatisation into the ready cycled tank of 1.010 , but seriously its not good long term for the fishes and i think its butt ugly combining the 2 types of fishes
