I had two blue ahli's that were nice and blue about 3 inches long. They both turned gray and started fighting so i got rid of one of them. It still has not blued up. Do people dye these things blue. I picked up to more last week they are great looking and about 3-3.5 inches. The LFS was suppose to send me females. The one is secretive and hangs out in the shadows and the other one swims free thoughout the tank.????????????
