Sorry about any page stretching I'm not real good with a iPad. So i moved in with my boyfriend and bought myself a little koi fish, the orange and black fish in the photos the rest of the fish he said he got two years ago from the feeder tank at petsmart. Four of those fish are much larger than the rest and are even shaped different, and one of the four has really pretty gold coloring. I was wondering what they are? Maybe just another type of goldfish but not sure, I got the best pics I could get sorry about quality.
