This guy is 5+ inches from spine to spine. His favorite foods include any species of ornamental macro algae - the more expensive the faster he will consume it. I got him about six months ago and he is still growing. Someone needs to take him off my hands before he eats my stand and canopy next. I'd really like to trade for some colorful zoas, palys and/or acans but I'd also sell for $45. I'll post a pic as soon as I can find my tape measure for reference
