A couple of days ago we came home and all that was left was a skeleton.I had recently got frustrated with algea and added some stuff to kill it.Would this stuff kill the Plecos?Would the two Pictus cats we have kill him?I figured he had allready died and they just ate the carcuss.I didn't realize the Algea kill stuff wasn't supposed to be used in a aquarium with live plants.So far it hasn't killed the plants or the algea.
