My LFS has a flounder for sale and I was thinking of getting it for my tank. It's about 4-5 inches in length, a coralish white/gray speckled color (one one side) and I think white on the other. It has these things all around it like little fringes. It's flat with it's eyes on the top. The LFS said it would probably be good for my tank cause it would help stir the sand. They also said they are easy to care for so I'm wondering if any of this is true? Any advice? I am thinking I may go back and get this fish but I want to see what's involved. Any info?
