Java Combtail

The Java combtail is the large Southeast Asian relative of the combtail from Sri Lanka. Its olive-brown or gray body carries a net-like pattern from the dark lines along the edges of its scales; the tail rays extend beyond the membrane, giving a comb-like appearance. It reaches 18–20 cm in the aquarium. It is a powerful, greedy and territorial fish; it is known to guard its young as a parent.

• At least 250 liters for a single fish, with a length of 120 cm or more.
• 24–27°C, pH 6–7.5; soft to moderately hard water.
• Large roots, rocks and hiding places; sturdy plants.
• A strong filter, weekly water changes of 25–30% and a tight lid.

Carnivorous. Give meat-based granules and pellets, frozen shrimp, mussels, bloodworms and worms. Feed in moderation once a day.

Aggressive toward its own species and territorial toward other fish. It hunts fish and shrimp that fit in its mouth. It is best kept in a species tank or with robust fish close to its own size.

Good companions: large, calm species such as large, robust barbs, large plecos and snakeskin gourami.

Avoid: small fish and shrimp, slow long-finned species, a second fish of its own species (in a small aquarium).
