Chili vs Strawberry vs Phoenix Rasbora Comparison Guide: Nano Picks
Three Boraras species sit on the same Iwarna shelf and look like the same red dot to anyone glancing at the bag. The chili vs strawberry vs phoenix rasbora question matters because each has subtle colour, size and behaviour differences that determine which scape they suit. This guide from Gensou Aquascaping at 5 Everton Park decodes the trio so your nano blackwater scape gets the exact micro rasbora you want.
Quick Verdict
Pick chili rasbora for the deepest blood-red colour and the smallest size, ideal for 30-litre blackwater scapes. Pick strawberry rasbora for a softer pink-red tone with larger body presence. Pick phoenix rasbora for an orange-red coppery shimmer that stands out against green carpets.
Chili Rasbora: The Tiny Red Showpiece
The chili rasbora (Boraras brigittae) is the smallest of the trio at 1.5-1.8cm and holds the deepest crimson colouration. Males display saturated blood-red flanks with a dark lateral stripe; females stay paler and slightly larger. Native to Borneo blackwater swamps, they thrive in pH 5.0-7.0, GH 1-5 and 24-28°C. School of 12 minimum to see proper colour — singletons and trios stay washed out. Ideal for tanks under 40 litres with floating aquarium plants and tannin-stained water.
Strawberry Rasbora: The Pink-Red Variant
Strawberry rasbora (Boraras naevus) reaches 1.8-2.2cm with a softer pink-red body and a distinctive black blotch mid-flank. They are slightly chunkier than chilis and the colour reads more salmon than crimson. Water requirements mirror chili — soft, acidic, warm — but they handle slightly harder Singapore PUB tap better. Group of 10+ for proper schooling. They are less commonly imported than chilis, so availability swings month to month at Iwarna and Polyart.
Phoenix Rasbora: The Orange-Red Glower
Phoenix rasbora (Boraras merah) hits 1.7-2cm with an orange-red copper sheen that catches light differently from the other two. Males show a fine black stripe and bright orange dorsal; females are stockier with diffused colour. Phoenix tolerates a wider pH band of 5.5-7.2 and is generally the hardiest of the three for new keepers. Group of 10+. They contrast beautifully against green carpets like monte carlo or HC Cuba.
Side-by-Side Spec Comparison
Size: chili 1.5cm, phoenix 1.7cm, strawberry 2cm — barely 0.5cm separates them but it shows in person. Colour: chili deep blood-red, strawberry pink-salmon, phoenix orange-copper. Hardness tolerance: phoenix most forgiving, chili most demanding. Minimum tank: all three work in 30 litres for a school of 10+. Bioload: negligible across all three. Price: chili SGD 2-4 each, phoenix SGD 3-5, strawberry SGD 4-7 because of import scarcity.
Decision Framework
If you want maximum red saturation and run a dedicated blackwater scape with botanicals, pick chili. If you need the hardiest option and your water is closer to neutral PUB tap, pick phoenix. If you want a slightly larger Boraras with a softer tone and you can find them stocked, pick strawberry. For a mixed display, chili plus phoenix work in the same tank — the red contrast looks deliberate. Avoid mixing chili with strawberry; the colours muddle.
Singapore Sourcing and Pricing
Iwarna stocks chili rasbora year-round at SGD 2-4 each, with packs of 10 around SGD 25-35. Polyart and ANS carry chili and phoenix interchangeably. Strawberry rasbora is the harder find — Iwarna gets them every 8-12 weeks at SGD 4-7 each. Carousell occasionally has wild-caught batches from Indonesian importers. Quarantine new arrivals for 2-3 weeks; wild stock often carries internal parasites. Add catappa leaves to ease the transition.
Common Mistakes
Stocking under-strength schools of 4-6 fish is the worst mistake — these micro rasboras lose colour, hide constantly and die from chronic stress within months. Second error: keeping them with anything larger than ember tetras or galaxy rasboras; even a peaceful 5cm fish triggers shoaling stress. Third: bare hardscape tanks with bright lighting wash the colour out completely. Use floating plants from the aquarium plants range and shaded tannin-stained water for proper colour expression.
