First time posting, read through the forums and didn't see an answer, so I thought i'd ask.

We have a 10 gallon tank, with 2 blue platys, 2 sunset mollys, and just added two male guppies. Water levels are fine, we got them tested at 2 different stores. PH is fine, and we just did a water change yesterday.

The problem is, the larger platy (more round, bigger belly, I can't tell if it's a female) is harassing the guppies. This mean fish is RELENTLESS. We don't have another tank to put him in, but he's non-stop nipping at the guppies. Parts of their tail are missing and the orange one is about to die. He floats like he's dead and then he'll start swimming a bit, and then floats again. I know he's going to kill the other guppy.

About a week ago we bought a Gourami and 3 Neons, and lost all of them due to aggression. At first I thought it was the Gourami that was nipping at the Neons, but then once he died, I thought differently.

We bought those 4 at Petco and they didn't tell us that we would have a problem with them, or that Platys are aggressive.

What can I do? The platy leaves the other platy alone, and Petco (where we got the Mollys and the Platys) gave us 1 male, 1 female. The platy only harasses the new fish.

I hate seeing the platy do this. It's not fair to the Guppies. lol Any ideas on what we can do?
