Gobies live in coastal waters. When they are
away from their shelters, they resist the
movement of the water by clinging on to rocks with
their pelvic fins, which are turned into suckers
(although there are exceptions to this). They are
easy to raise and feed on small, live prey.
Lythrypnus dalli
The Catalina goby, a small species native to
California, can be distinguished by its vertical
blue bands. It lives in harmony with
invertebrates. Size: 4 cm. •
Nemateleotris magnifica
The fire goby, native to the Indo-Pacific
region, more than lives up to its Latin name
of magnifica. It adapts well to captivity but
remains somewhat timid, and so it must be
kept with placid species, or in an
invertebrate tank. It accepts artificial food.
Several species from the same genus, with
similar vivid coloring, are sometimes found
on the market. Size: 10 cm.
