Overview
- Native to the Indo-Pacific region, particularly found in coral reefs.
- Recognized for its vibrant yellow coloration and small, stocky body.
- Peaceful and reef-safe, making it a great addition to nano and reef tanks.
- Often seen perching on coral branches, where it establishes a territory.
- Displays strong site fidelity, preferring to remain within a small area.
Feeding
- Carnivorous diet, primarily feeding on planktonic crustaceans and small invertebrates.
- Readily accepts high-quality frozen and live foods such as brine shrimp and mysis shrimp.
- Supplementing with finely chopped seafood enhances health and coloration.
- Can adapt to pellet and flake food but prefers a varied diet.
- Multiple small feedings per day support their high metabolism.
Habitat
- Commonly found in branching corals such as Acropora species.
- Prefers calm reef environments with ample hiding spaces.
- Requires a well-established tank with stable water parameters.
- Best kept in tanks with live rock and coral structures to mimic its natural habitat.
- Ideal for nano tanks but thrives in larger reef setups as well.
Fish Care
- Optimal water temperature: 74-80°F (23-27°C).
- Ideal pH range: 8.1-8.4, with a specific gravity of 1.023-1.026.
- Requires stable water quality and low-stress conditions.
- Prone to being outcompeted for food by faster-moving tank mates.
- Regular water changes help maintain optimal health and coloration.
Compatibility
- Highly peaceful and best suited for non-aggressive community tanks.
- Compatible with other small, peaceful fish such as clownfish, gobies, and firefish.
- Should not be housed with aggressive species or large predatory fish.
- May be territorial towards other gobies, particularly of the same species.
- Safe with corals but may occasionally nip at polyps in stress situations.
Aquarium Behavior
- Spends much of its time perched on coral or rock formations.
- Curious and social but not highly active swimmers.
- Forms strong bonds with its environment and may establish a favorite perch.
- Can be shy initially but becomes more confident with time.
- Does well in pairs or small groups if introduced properly.
