He is killing any fish that I put in the tank,first I had two Silver mollies in ther and he killed 1,the other 1 died because it commited suicide....then I put in two Golden-Speckled Platies,he killed both of them....

Right now I only have my male swordtail and my female swordtail in there.

It's a 10 gallon tank

he is killing platys and mollies because he is harrasing them because they are so close. he wants to breed with them so he is chasing them and harrassing them.

the 10g would only fit about 5 swordtails, or platys, or mollies in there just to let you no.
