Overview

The tiger goby is a small, peaceful reef goby ringed with thin bars. It is an easy fish for a first reef tank.

Did you know

The tiger goby is more at home in a tide pool than almost any other reef fish. In the wild it is often found in water shallow enough to wade in, hiding under red algae between tides.

Caring for the tiger goby

The tiger goby is content in a nano tank of at least 11 gal (40 L). Each fish adopts a favorite crevice in the rock and darts out from it for food. Keep the water at 72 to 81°F (22 to 27°C) with a pH of 8.1 to 8.4.

Tiger gobies are peaceful and reef safe, and they mix well with other community fish. They tolerate their own kind better than most small gobies, so singles, pairs and small groups all work. Breeding them is moderately difficult.

Good to know

The tiger goby is currently placed in Tigrigobius, a genus name that literally means tiger goby. The trade still lists it under its older name, Elacatinus macrodon. Its body is translucent with a greenish cast, ringed from snout to tail with thin brown bars.

In the wild

The tiger goby is a shallow water goby of the subtropical western Atlantic, from southern Florida to northern South America. It has been recorded down to about 7 m. It holds close to rock faces, pilings and the surfaces of large sponges.
