Blue Neon Dwarf Goby - Stiphodon atropurpureus

Blue Neon Dwarf Goby (Stiphodon atropurpureus)

The Blue Neon Dwarf Goby (Stiphodon atropurpureus) is a stunning freshwater fish known for its vibrant blue coloration and active, inquisitive behavior. Native to fast-flowing streams in Southeast Asia, this small goby is highly sought after by aquarists for its unique appearance and peaceful temperament.

Description:

• Common Name: Blue Neon Dwarf Goby

• Scientific Name: Stiphodon atropurpureus

• Family: Gobiidae

• Size: 1.5-2 inches (4-5 cm)

• Color: Males display a striking blue or blue-green body with dark markings, while females tend to be less colorful, with pale brown or greyish tones.

Native Region:

Blue Neon Dwarf Gobies are found in tropical streams and rivers in Japan, Taiwan, the Philippines, and parts of Southeast Asia. They inhabit fast-flowing waters with rocky substrates, where they graze on algae and biofilm.

Aquarium Setup:

• Tank Size: Minimum of 10-20 gallons (40-75 liters), especially if keeping a small group.

• Water Parameters:

• Temperature: 72-80°F (22-27°C)

• pH: 6.5-7.5

• Hardness: Soft to moderately hard water (4-12 dGH)

• Diet: Primarily herbivorous; they feed on algae, biofilm, and detritus in the wild. In captivity, offer algae-based wafers, blanched vegetables like spinach or zucchini, and supplement with small protein-based foods like brine shrimp or daphnia.

Care Level:

• Difficulty: Moderate

• Temperament: Peaceful and shy; they do well in community tanks with other small, non-aggressive species.

• Lifespan: 3-5 years with proper care.

Behavior:

The Blue Neon Dwarf Goby is an active yet peaceful species. Males may become territorial, especially during breeding, but overall they are excellent community fish. They are bottom dwellers, often seen perching on rocks or substrate, grazing on algae.

Additional Tips:

• Tank Mates: Suitable tank mates include other peaceful fish like tetras, rasboras, and small Corydoras species. Avoid aggressive or boisterous fish that could outcompete them for food or stress them.

• Feeding: Provide a diet rich in algae and plant-based foods to mimic their natural diet. They may not eat much prepared fish food, so supplementing with natural algae growth in the tank or adding algae wafers is essential.

• Breeding: In the wild, Blue Neon Dwarf Gobies migrate to brackish water to breed, making reproduction in home aquariums challenging.
