Thanks, Dogstar. Your pic is helpful. I have had mine now for about 1 year. He has grown about 1-2 inches all the way around. Sure is a pig though, loves his algae sheets. Him and the rabbitfish look like they are eating spaghetti with the sheets....one on each end!!! Sure is a sight.
I was at the LFS today and saw the tiniest sailfin for sale, 2-3 inches at the most and it was completely white with brown already. Just a thought, could it be where it is caught? Or diet? Gender? Don't know, but just wondering why some stay yellow for so long and others turn white much quicker. Inquiring minds want to know.......
