Compatibility brief
Can Chili Rasbora live with Rainbow cichlid?
Risky. This mix is commonly discouraged for typical setups.
Chili Rasbora + Rainbow cichlid: Rainbow cichlid may eat Chili Rasbora. Rainbow cichlid (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.
Compatibility score
Profile confidence: medium
Order of checkstank volume vs adults → predation mouth gap → temperament / fin nipping → shared water windows.
200L
Combined minimum footprint reference for these two species: about 200L (larger active fish often want more length).
Rainbow cichlid (12cm adult) may treat small Chili Rasbora (~2cm) as food once grown — plan adult sizes, not shop 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.
