I bought it yesterday at the same retailer as I got my platys. I've had 4 platys and 2 swordtails for about one month now. When I came home the day after I got it, two of my platys, who had been doing fine were dead. I can only assume it was the angelfish since I've heard they are aggressive in nature. Extra: Both platys killed were pregnant. I now have 2 remaining female platys (also both pregnant as far as I know), one female swordtail and one male swordtail. The angelfish is pretty small about 2 inches tall, and my platys and swordtails are about 1 1/2 inches long.
