At Meijer they were called "Parrot Fish". As long as I have had them they are about 2 inches in diameter and are pretty oval like. They come in solid colors, I have pink, yellow, and blue. They have odd shaped mouths for the freshwater fish ive seen but maybe it sjust me. They tend to stay together and huddle up when I approach the tank. Any ideas? Ill get a pic if I can get a hold of a digital camera.
