Why Choose a Firefish Goby?

The Firefish Goby boasts a dazzling gradient of orange, yellow, and purple hues with a sleek, dart-like body that makes it a showstopper in nano and reef aquariums. Its tendency to “hover” in the water column makes it a joy to watch.

These fish are peaceful and community-friendly, making them excellent tank mates for other small reef-safe species. They prefer live rock for hiding and will establish a safe territory if the tank setup allows.

🧠 Pro Tip:

Firefish Gobies are known jumpers! Ensure your tank has a secure lid or mesh top to prevent escape. They’ll thrive in tanks with plenty of rockwork and low-aggression neighbors.
