Indian Spike Tail Paradise Fish

Indian Spike Tail Paradise Fish (Pseudosphromenus dayi) is a smaller and considerably more peaceful relative of the true Paradise Fish — belonging to a different genus entirely. The elongated central caudal fin rays form a distinctive spike-like tail extension that gives this fish its name. The body displays warm brown and cream tones with iridescent highlights. Unlike Macropodus species, this fish is genuinely community-friendly.

Feeding & Care Tip: Sera Vipan Tropical Flakes and Hikari Micro Pellets make excellent daily staples. Supplement 2–3× per week with Hikari Frozen or Freeze-Dried Baby Brine Shrimp or Hikari Vibra Bites. Feed small amounts 2–3 times daily in a planted setup.

Native to slow-moving, heavily vegetated streams and rivers of southwestern India and Sri Lanka. Inhabits soft, slightly acidic blackwater environments with dense planting and leaf litter. A planted aquarium with tannin additions produces the most relaxed and vividly colored fish.

Keep in pairs or small groups. Far more peaceful than true Paradise Fish — can be kept in planted community setups with other peaceful species. Males build small cave or surface bubble nests and guard the eggs.

Males build floating bubble nests at the surface among plants or floating vegetation when in breeding condition — a fascinating and distinctive behavior. The male courts the female with elaborate fin displays, and the pair spawns beneath the nest. The male guards eggs and wriggling larvae until the fry become free-swimming. Remove the female after spawning to protect her from the male's nest-guarding aggression. All gouramis possess a labyrinth organ — a specialized breathing structure above the gills that allows them to breathe atmospheric air directly from the surface. This adaptation evolved for life in oxygen-poor waters and means gouramis can survive in conditions that would stress most other fish. Always ensure unobstructed surface access — a tight-fitting lid with a small gap, or a covered aquarium, prevents the fish from breathing cold air which can cause respiratory issues.
