What??? He needs a water softener? You can only keep one male in a tank?
At first when introducing a new ray stuff probably will happen but they need to settle in. Just like any other fish they are very curious creatures.
And before you go getting a water softener unit find out about what other accomplished ray keepers in your area are doing and using.
Pics would help. But fresh water and pre dissolved (pure 100% )salt in water will do allot.
Guess I'm breaking all the rules.
You should try to use some kind of water softener, but you have to be very careful because rays are very sensitive if you have an extra tank pass the injured ray to the new tank and treat it there. Also you should never keep more than 1 male ray together. You have 3 males and 2 females. When having rays you should aim to have trios, 1 male and 2 females so when they´re breeding the male disperses his aggression too both females.
