This is the first time I actually seen my Tuxedo with absolutely nothing on him.... lol Usually, he is toting some shells, rocks, sand and sometimes a snail. I love him, he is so pretty.
lookin good, but make sure to watch him. you dont want that to be a regular behavior. the debris they carry is a sign of good health. If your urchin is not carrying things its possible he is not happy.
i had one to eat all the algae i had. then he consumed all of that(good lord could he eat) so he started eating my coraline. i decided i couldnt feed him enough so i sold him back. i didnt want him to die from starvation.
