They had them at their store for about 6 months, they came in healty but they just quit feeding them or taking care of them at all for that matter. The water was so green we had to move a net around to get them to the front of the tank so we could see them to catch them. They came from the same place our big female came from so yea they were healthy. We've had them for about a month now and they're eating shrimp, scallops, nightcrawlers and blood worms, and the occasional angelfish that they catch while swimming up the glass lol. I'm raising angels to get big for our other fish store here and he didn't think that the rays would get them haha.
