Scientific Name: Boraras naevus
Common Names: Strawberry Rasbora, Strawberry Dwarf Rasbora
Family: Cyprinidae
Origin: Southern Thailand (Trang & Satun provinces)
Habitat: Slow-moving forest streams, shallow peat swamps with dense vegetation, soft sandy bottoms, and leaf litter.
Size: Around 1.5–2 cm (very small nano fish)
Lifespan: 4–6 years with good care
Small, slender body with a pinkish to reddish hue, resembling the color of a strawberry.
Iridescent scales with tiny darker spots or blotches.
Transparent fins with light red or orange tinge.
Color intensifies in males and during breeding.
| Parameter | Ideal Range |
|---|---|
| Temperature | 22–28°C (72–82°F) |
| pH | 5.0–7.0 (slightly acidic preferred) |
| Hardness | 1–8 dGH (soft water) |
| Ammonia/Nitrite | 0 ppm |
| Nitrate | < 20 ppm |
They thrive best in tannin-rich, soft, acidic water like their natural peat swamp habitat.
Tank Size: Minimum 20 liters (5 gallons) for a group.
Substrate: Dark sand or fine gravel.
Decoration: Driftwood, leaf litter, live plants (Java Moss, Cryptocoryne, Anubias, floating plants).
Lighting: Low to moderate (brings out colors).
Filtration: Gentle sponge filter to avoid strong currents.
Aquascaping Tip: Dense plants + shaded areas mimic their natural environment.
Peaceful and shy; ideal for nano & community tanks with similarly small, non-aggressive fish.
Best kept in schools of at least 8–10 for confidence and natural behavior.
Mid to upper water swimmer.
Type: Micro-predator (feeds on tiny zooplankton & insect larvae in the wild).
In Captivity:
Live/frozen: Baby brine shrimp, daphnia, microworms
High-quality micro pellets
Crushed flakes
Cyclops, grindal worms
Feed small portions 2–3 times daily.
Type: Egg scatterer, no parental care.
Breeding Tank: Separate tank with fine-leaved plants or spawning mops.
Conditioning: High-quality live food to trigger spawning.
Process:
Male chases female; eggs are scattered among plants.
Adults should be removed after spawning to prevent egg predation.
Eggs hatch in 24–48 hours; fry are free-swimming in 3–4 days.
Fry Food: Infusoria initially, then microworms and baby brine shrimp.
Keep in a calm, stable environment—avoid large aggressive tankmates.
Perform small, regular water changes (20–30% weekly).
Use Indian almond leaves for tannins and health benefits.
Provide a tight lid; they can jump.
