The Honeycomb Combtail, scientifically known as Belontia hasselti, is a captivating freshwater fish native to the slow-moving waters and still ponds of Southeast Asia, including Indonesia, Thailand, and the Malay Peninsula. This species belongs to the gourami family and is appreciated for its unique appearance and interesting behaviors, making it a fascinating addition to the home aquarium for intermediate to advanced fish keepers.

One of the most striking features of the Honeycomb Combtail is its coloration and fin structure. The body of the fish showcases a beautiful pattern reminiscent of a honeycomb, with shades of brown, gold, and sometimes green, creating a mesmerizing effect. The fins, particularly the caudal fin, are elongated and edged with a delicate, comb-like appearance, which is the origin of the common name "combtail." This species can reach a considerable size in the aquarium, adding to its presence and appeal.

Belontia hasselti is known for its territorial behavior, especially among males. It is important for aquarists to provide ample space and proper tank conditions to minimize aggression. A well-planted aquarium with hiding spots and territories can help in this regard, simulating the dense vegetation of their natural habitat and providing areas for retreat. Despite their territoriality, with careful management, they can be kept with other peaceful and similarly sized species that occupy different areas of the tank.

The care requirements for the Honeycomb Combtail include maintaining clean, slightly acidic to neutral water with moderate hardness. The tank should be equipped with a gentle filtration system to replicate the calm waters of their natural environment, and the temperature should be kept within the tropical range to ensure their health and comfort. Floating plants and subdued lighting can also help mimic their natural habitat, providing a sense of security and encouraging natural behaviors.

In terms of diet, the Honeycomb Combtail is omnivorous, requiring a varied diet that includes both plant-based foods and protein sources. High-quality flake foods, pellets designed for omnivorous fish, along with regular offerings of live or frozen foods like brine shrimp, daphnia, and bloodworms, will help keep them healthy and vibrant. Vegetable matter, such as blanched spinach or zucchini, can also be offered to supplement their diet.

Breeding the Honeycomb Combtail can be challenging due to their territorial nature and specific water condition requirements. Like many gouramis, they are bubble nest builders, with the male constructing a nest at the water surface from plant debris and bubbles. After spawning, the male tends to the eggs and fry, displaying fascinating parental behaviors. Aquarists interested in breeding this species should prepare a dedicated breeding tank to accommodate these unique behaviors and ensure the safety of the fry.

Overall, the Honeycomb Combtail offers a blend of beauty, intriguing behaviors, and a bit of a challenge, making it a rewarding choice for the more experienced aquarist looking to add a distinctive and engaging species to their collection.
