Compatibility brief

Can Chili Rasbora live with Silver dollar?

VerdictRISKY

Risky. This mix is commonly discouraged for typical setups.

Chili Rasbora + Silver dollar: Silver dollar may eat Chili Rasbora. Silver dollar (12cm) is predatory and Chili Rasbora (2cm) is small enough to be eaten. This pairing is unsafe. Real tanks add variables Fishori cannot model; treat this as a high-risk read, not certainty.

  • Chili Rasbora should be kept in a group of at least 8 for best health and behaviour.
  • Silver dollar should be kept in a group of at least 5 for best health and behaviour.
  • Build a species-only tank for the larger fish, or restock with fish too large to be eaten at adult sizes.

Plan further

Try both species in the full-stock tank check, or open either fish profile for mates lists. Methodology explains how verdicts are produced.

Individual fish vary in personality. Fishori uses conservative hobby rules. Observe any new introduction closely, feed thoughtfully, and keep a quarantine or backup plan. This is not veterinary advice.

Profile data confidence: high. Based on multiple reputable aquarium care sources with strong agreement.
