Invertebrates
Short-Spine Sea Urchin.
A rounded, hard-working grazing urchin with a dense coat of short, sturdy spines rather than long needles. These urchins are diligent algae eaters that scrub rock and glass as they move, and they often carry bits of shell or debris on top for camouflage. A useful and hardy member of a saltwater cleanup crew.

We never ship fish, coral, or invertebrates — every animal here is one you meet in person. Each one is acclimated and health-checked in-house before it goes out into the display tanks. This is a species we keep, and what is swimming on any given day changes with the deliveries, so please call (814) 456-9445 before you drive in.

Peaceful toward fish and other invertebrates, though as it grazes it may nudge or knock over loose corals and frags.
Good to know
Short-spine urchins often decorate themselves with shells, rubble, or bits of algae, holding the debris in place with their tube feet.
