PENCIL URCHIN (Heterocentrotus
mammillatus). The Slate Pencil Urchin, also known as Red
Slate Pencil Urchin, has a reddish-tan body with sparse, long, blunt
solid spines that taper at the tips and radiate out from the body in
all directions at lengths of up to five inches. In addition to its
spines looking like pencils, this sea urchin is also called the
Slate Pencil Urchin because its spines were used as writing utensils
for slate boards. It can move about via its suctorial podia. It has
enough traction to allow it to climb up the glass sides of an
aquarium. Because of its large size, the Slate Pencil Urchin will
require the solid construction of rocky reefs in the aquarium; rock
pieces should be well placed to avoid accidental tumbling and moving
around. It can be destructive and harmful to corals, but is safe in
a fish-only aquarium. Slate Pencil Urchins are generally solitary,
and it is generally best to keep just one of its kind per tank.
Being nocturnal, it will usually hide during the day and wait for
the cover of night to forage for algae. Live rock will provide a
good source for grazing. The Slate Pencil Urchin prefers low nitrate
levels and will not tolerate copper-based medications. It is not
unusual for it to lose a few spines, but if it sheds quite a few of
them, it is often due to poor water quality.

RED GROUPER (Cephalopholis
miniatus). Red groupers are easily recognized by their
color and by the sloped, straight line of their spiny dorsal fin.
The fin has a long second spine and an unnotched interpine membrane.
Most epinepheline groupers have a notched dorsal spine membrane and
a third spine longer than the second. The body is deep brownish-red
overall, with occasional white spots on the sides. Tiny black specks
dot the cheeks and operculum. The red grouper is most closely
related to the Nassau grouper, Epinephelus striatus, which has
several vertical bars and blotches, and is found more commonly on
coral reefs. It inhabits ledges, crevices, and caverns of rocky
limestone reefs, and also lower-profile, live-bottom areas in waters
10 to 40 feet deep. The red grouper is a protogynous hermaphrodite,
and females are capable of reproducing at 4 years of age. The
maximum age of the red grouper is 25 years, with older fish reaching
a size of 32.5 inches and 25 pounds. Red groupers usually ambush
their prey and swallow it whole, proffering crabs, shrimp, lobster,
octopus, squid and fish that live close to reefs. (http://www.safmc.net/FishIDandRegs/FishGallery/RedGrouper/tabid/313/Default.aspx
