Rio Grande perch are a cichlid, a distant cousin to tilapia. They are native to the Rio Grande River watershed. They don't like cold water, will bite a hook, and are pretty cool fish, not normally for sale from a fish farm. They aren't a typical pond stocking fish, since they are semi-tropical and can't support a predator base by themselves. They are like the sprinkles on the icing of the cake. Enjoy them.
