I bought what they call a flounder at the lfs. I was trying to figure out what it will need to eat and how big it would get. I was reading on here and someone said that a ray has a gill behind it's eyes, but this "flounder" has one as well. It is in a freshwater tank. It is somewhat active. It either lays on the bottom or sticks to the side. It has two eyes on the top of it. It is white with dark spots when the light is on. When the lights are off it is brown. If anyone has any info it would be greatly appreciated.
