MM Platy - aggressive?

In our newer 40gal tank over the last couple weeks we introduced a MM Platy and a number of smaller fish.

A couple have died but looked beat up to me. Tonight I was watching a glofish danio and it was fine. A couple hours later he was clearly injured and looked beat up. While watching the tank the MM Platy cam by and nipped him.

A while later someone else noticed the MM Platty nipping some other fish.

Are they normally aggressive fish? There are two other platies in the tank and they are quite passive.

I think I will be returning the MM PLaty to the store tomorrow, as well as exchanging the now dead glofish.

Is it worth getting another Platy or should I just get something a bit more passive?

IME, sometimes a platy will be a bit aggressive, but not usually. I think its worth it to trade for a different one. I suggest getting a female instead. I have never had a nippy female.

They are not aggressive, but they do like to a buddy to swim around with
