Spike-tailed Paradise Fish

The spike-tailed paradise fish is recognized by the rays in the middle of its caudal fin, which form a short pointed tip. It grows to about 6 cm; its body is reddish brown and its fins are edged with blue. It lives in shallow, vegetated waters on the coastal plains of southeastern India and Sri Lanka; some populations also tolerate slightly brackish water. With its calm nature and hardiness, it is a good labyrinth fish for small aquariums.

• At least 30 liters for a pair.
• 24–27°C, pH 6–7.5; soft to moderately hard water.
• Dense plants, floating plants, and small caves or broad leaves as nest sites.
• Weak flow and a tight lid; warm air above the surface.

Carnivorous. It accepts small granules and flakes; supplement with frozen and live bloodworms, brine shrimp, daphnia and mosquito larvae. Feed small amounts 1–2 times a day.

Peaceful and somewhat timid. The male builds his bubble nest on the ceiling of a cave or under a leaf and guards the eggs. It may eat shrimplets; it does not harm adult fish.

Good companions: small, calm fish: harlequin rasbora, pencilfish, small tetras, kuhli loach, otocinclus, dwarf corydoras.

Avoid: fast, greedy schools, fin nippers, large gouramis, aggressive cichlids.
