Compatibility brief
Can Angelfish live with Checkerboard cichlid?
Risky. This mix is commonly discouraged for typical setups.
Angelfish + Checkerboard cichlid: Incompatible pH requirements. Angelfish prefers pH 6.5–7.5 and Checkerboard cichlid prefers pH 3.5–5.5. Their ranges do not overlap. 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.
150L
Combined minimum footprint reference for these two species: about 150L (larger active fish often want more length).
Angelfish (20cm adult) may treat small Checkerboard cichlid (~5cm) as food once grown — plan adult sizes, not shop sizes.
Temperament gap (semi-aggressive vs peaceful) — can work with space, structure, and careful observation, but not a “drop and forget” mix.
Assessment details
Temperament difference
Angelfish is semi-aggressive, while Checkerboard cichlid is peaceful. This can work with adequate space and hiding spots, but monitor for bullying.
Compatible temperature range
Both fish can comfortably share similar water temperatures.

- •Provide plenty of hiding spots and visual breaks so Checkerboard cichlid can escape if harassed.

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.
