I don't have any decent pictures of my conchs, but the queen looks a little different from the fighting one. It also acts different. The fighting conch (1-1/2" long) has several subtle bumps protruding around the largest diameter point of its shell. The queen (1-1/4") has noticeably sharper points around the same area of the shell. The fighting conch never leaves the sandbed. The queen will at times go on the rocks or the glass, although it spends most of the time on the sand. Mine are growing very slowly, but I don't think they get much to eat. My sand has a lot of diatoms, but nothing else for them.
