unusual clean up crew

[hobogato]

maybe what you read doesnt apply to all species of fromia, the rocks seem visibly cleaner after it crawls over? we had one last year in the classroom that looked just like this one and it lived from october to the end of the school year - i dont remember who bought it from the students.

i just dont think the longspine urchin will be safe for the cuttles if they get startled and jet into or around the rocks. i will likely get a tuxedo or two instead. this one will go to my dad's tank.

the real algae cleaner is the sea hair.

as far as the oyster, i guess any filter feeder could be considered as a part of the cleanup crew...
