Peacock Goby
A small, jewelled gudgeon in blue and yellow with red-edged fins and a dark eyespot at the tail base. Cave-spawning, characterful and one of the best small fish for a quiet planted tank.
Feeding
Prefers meaty foods. Frozen bloodworm, daphnia and brine shrimp, plus quality micro-pellets. Often refuses dry flake.
Compatibility
Peaceful but not a shoaler. Keep as a pair or a small group with plenty of caves so each male has territory. Best with calm, slow-feeding tankmates.
Behaviour and personality
Perches and hops between vantage points rather than swimming constantly. Males defend a cave and colour up hard when displaying.
Before you buy
Will often ignore flake entirely, so budget for frozen food. Provide more caves than you have males, or risk territorial disputes.

The Peacock Goby is a striking addition to my planted tank. It’s active but not noisy, and the bright colors stand out well. I feed it frozen bloodworms daily and it’s very accepting. The males are calm when not displaying, and I’ve provided several caves to avoid conflicts.

I bought this fish for a quiet tank setup, and it fits perfectly. It doesn’t eat flake, so I switched to frozen foods. The fish is very curious and hops around the rocks. I keep it with a few slow-moving species and it’s peaceful.

A beautiful and unique fish. It’s very active in its perching behavior and shows off its colors when defending its cave. I made sure to have more caves than males, and it’s been a stable addition to my tank for over six months.
