- Water Conditions: Banded Gudgeons prefer freshwater aquariums with a temperature range of 75°F to 82°F (24°C to 28°C). They thrive in slightly acidic to neutral water with a pH level between 6.5 and 7.5. A well-filtered tank with regular water changes is essential to maintain optimal water quality and provide a healthy environment for these fish.

- Tank Size and Setup: Banded Gudgeons are relatively small, reaching an average length of 3-4 inches (7-10 cm). A tank with a minimum capacity of 20 gallons (75 liters) is suitable for a small group of these fish. Provide plenty of hiding spots with dense vegetation, caves, or driftwood to mimic their natural habitat. They appreciate subdued lighting and a peaceful environment.

- Tank Mates: Banded Gudgeons are generally peaceful but can be territorial toward their own species, especially during breeding. They are best kept in a species-only setup or with peaceful, similarly sized tank mates. Avoid housing them with fin-nipping or aggressive species that may harass or stress them. Suitable tank mates include small tetras, rasboras, dwarf cichlids, and peaceful bottom-dwelling catfish.

- Feeding Habit: Banded Gudgeons are carnivorous and primarily feed on small live or frozen prey. They have a voracious appetite and eagerly consume small insects, worms, and crustaceans. In the aquarium, they can be fed a varied diet consisting of high-quality frozen or live foods such as bloodworms, brine shrimp, daphnia, and small insects. It is essential to provide a diverse and nutritious diet to ensure their optimal health and vitality.

- Care and Behavior: Banded Gudgeons require diligent care and attention. They are shy and prefer a quiet and well-established aquarium. Dense vegetation and hiding spots help them feel secure. These fish are jumpers, so a tightly fitted lid is necessary to prevent escape. Regular water changes, maintenance of water parameters, and a balanced diet contribute to their well-being and vibrant colors.

- Breeding: Breeding Banded Gudgeons in captivity can be challenging. They are bubble nest builders, and males exhibit elaborate courtship behaviors. Provide them with a separate breeding tank with gentle water flow, ample floating plants, and a substrate for nest building. The water temperature should be around 79°F (26°C). Once the female lays eggs, the male will guard the nest and tend to the fry. It is recommended to remove the female after spawning to prevent aggression.

In conclusion, Microctenopoma fasciolatum, the Banded Gudgeon, is an intriguing and visually captivating fish for the aquarium. With their unique appearance and interesting behavior, they are sure to draw attention. By creating an appropriate environment with suitable tank mates, providing a varied diet, and ensuring optimal water conditions, you can enjoy the beauty and fascinating nature of Banded Gudgeons in your aquarium.
