Overview

The green belly goby is a small, peaceful stream goby that needs a fast river tank. It is a demanding fish for experienced keepers.

Did you know

Male green belly gobies can repaint themselves in seconds during display, so the green belly shows their mood.

Caring for the green belly goby

Green belly gobies need a properly built river tank, and they will not tolerate compromise on flow. Keep a small group in at least 14 gal (54 L), over cobble with strong circulation and high oxygen. Run the turnover high enough to keep the surface broken.

Hold the water at 73 to 81°F (23 to 27°C), with a pH of 6.5 to 7.8. The green belly goby takes small meaty frozen foods and also grazes film off the stone.

It is peaceful, but keep it with other rheophiles, fish that like strong current, rather than in a general community. Color develops slowly over weeks once it settles, so a plain-looking new arrival is normal. Males show a green to blue belly against a dark forebody.

Good to know

Lentipes ikeae is a goby in the family Oxudercidae, also known as the ikeae goby or blue belly red goby. Lentipes are famous climbers. Juveniles returning from the sea scale vertical wet rock and waterfalls using a pelvic sucker. That climb is how they reach habitat with no other fish in it.

In the wild

Lentipes ikeae comes from steep, fast streams in western Sumatra. It usually lives well upriver, above waterfalls that keep out most other fish.
