Combtail

The combtail is a labyrinth fish endemic to the forest streams of Sri Lanka. It is named for the rays of its caudal fin, which extend beyond the membrane and resemble the teeth of a comb. With its reddish-brown, deep, laterally compressed body, it reaches 12 cm. Although it is a relative of the gouramis, its character is closer to that of cichlids: it establishes a territory and guards its mate and young.

• At least 150 liters for a pair, with a length of 100 cm or more.
• 24–27°C, pH 6–7.5, soft to moderately hard water.
• Areas divided with roots, rocks, caves and sturdy plants.
• Gentle flow and a tight lid.

Carnivorous and greedy. Give granules, frozen bloodworms, shrimp, mussels and mosquito larvae. Feed in moderation 1–2 times a day.

Territorial toward its own species and similar fish; it becomes harsher especially in the breeding season. It hunts fish and shrimp that fit in its mouth. It can be kept with robust fish close to its own size.

Good companions: medium to large robust barbs, large rasboras, bristlenose pleco, large corydoras species.

Avoid: small fish and shrimp, slow long-finned species, gouramis and bettas.
