I wonder if anyone could ID this urchin. I previously had a single blue tuxedo and since I have a ton of hair algae I wanted to get a second one to help clean up the tank. LFS owner insisted this was a red tuxedo. Any idea what this is and also what it eats? If it eats algae and not coral I don’t mind keeping it. It’s a little under 2 inches in diameter, spines are not sharp or painful to handle. It doesn’t wear things for camouflage and I can’t tell if it’s eating algae but it is fairly active both day and night
Google AI suggests Salmacis bicolor but I’ve never seen that listed for sale anywhere
