Compatibility brief
Can Chili Rasbora live with Firemouth Cichlid?
Risky. This mix is commonly discouraged for typical setups.
Chili Rasbora + Firemouth Cichlid: Firemouth Cichlid may eat Chili Rasbora. Firemouth 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).
Firemouth Cichlid (12cm adult) may treat small Chili Rasbora (~2cm) as food once grown — plan adult sizes, not shop sizes.
Temperament gap (peaceful vs semi-aggressive) — can work with space, structure, and careful observation, but not a “drop and forget” mix.
Assessment details

Next steps
Concrete changes, not "research more" filler.
- •Provide plenty of hiding spots and visual breaks so Chili Rasbora can escape if harassed.
- •Chili Rasbora should be kept in a group of at least 8 for best health and behaviour.
- •Firemouth Cichlid should be kept in a group of at least 6 for best health and behaviour.

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.
