Tank Requirements

Minimum Tank Size: 40 litres

Temperature: 24–28°C

pH: 6.5–7.5

GH: 4–12

KH: 2–8

TDS: 100–200 ppm

Neon Blue Gobies prefer clean, stable water with gentle flow and excellent oxygenation. They are sensitive to poor water quality, so regular maintenance is essential.

Habitat Setup

Recreate their natural riverine habitat with:

• Sand or fine gravel substrate (smooth surfaces to prevent injury)

• Live plants and mosses for cover

• Smooth rocks for perching and grazing

• Moderate, gentle water flow

They enjoy small hiding spots and shaded areas under plants or driftwood.

️ Feeding

Neon Blue Gobies are primarily herbivorous but will accept varied diets:

• Algae wafers or sinking micro pellets

• Blanched vegetables (zucchini, spinach)

• Occasional frozen foods (daphnia, baby brine shrimp)

Feed small portions 1–2 times daily, ensuring food reaches the bottom.

Tank Mates

Neon Blue Gobies are peaceful and social, best kept in groups of 3 or more.

Ideal companions:

• Small Rasboras

• Tetras

• Corydoras

• Small peaceful shrimps

Avoid:

• Aggressive or large predatory fish

• Species that compete for bottom territory

⚠️ Behavioral Note: They are territorial over small areas of substrate, so multiple hiding places reduce conflicts.

Breeding

Breeding is challenging.

• Typically occurs in flowing streams in nature

• Eggs are deposited on smooth surfaces

• Fry require small live foods such as infusoria

Most hobbyists maintain Neon Blue Gobies primarily for display rather than breeding.

Sexing / Identification

Males:

• Brighter, more intense blue coloration

• Slightly larger and elongated fins

• More territorial

Females:

• Duller blue

• Smaller body size

• Shorter fins
