Overview
Tiger gobies are peaceful, reef safe, and content in a nano tank, where each fish adopts a favorite crevice and darts out for food. They tolerate their own kind better than most small gobies, so singles, pairs, and small groups all work.
In the wild
A shallow water goby of the subtropical western Atlantic, from southern Florida to northern South America, recorded from tide pools down to about 7 m. It holds close to rock faces, pilings, and the surfaces of large sponges, often tucked under mats of red algae.
Good to know
It is currently placed in Tigrigobius, a genus name that literally means tiger goby, though the trade still lists it under its older name Elacatinus macrodon. The body is translucent with a greenish cast and ringed from snout to tail with thin brown bars, topping out near 5 cm.
Did you know
Few reef fish are as much at home in a tide pool as the tiger goby. In the wild it is often found in water shallow enough to wade in, hiding under red algae between tides.
