Compatibility brief

Can Angelfish live with Green neon tetra?

VerdictRISKY

Risky. This mix is commonly discouraged for typical setups.

Angelfish + Green neon tetra: Angelfish may eat Green neon tetra. Angelfish (20cm) is predatory and Green neon tetra (2.5cm) 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.

Combined minimum footprint reference for these two species: about 150L (larger active fish often want more length).

Size / predation

Angelfish (20cm adult) may treat small Green neon tetra (~2.5cm) as food once grown — plan adult sizes, not shop sizes.

Temperament / behaviour

Temperament gap (semi-aggressive vs peaceful) — can work with space, structure, and careful observation, but not a “drop and forget” mix.

Assessment details

  1. Temperament difference

    Angelfish is semi-aggressive, while Green neon tetra is peaceful. This can work with adequate space and hiding spots, but monitor for bullying.

  2. Angelfish may eat Green neon tetra

    Top issue

    Angelfish (20cm) is predatory and Green neon tetra (2.5cm) is small enough to be eaten. This pairing is unsafe.

  3. Compatible temperature range

    Both fish can comfortably share similar water temperatures.

  4. Narrow pH overlap

    These fish can share water but their ideal pH ranges overlap only slightly. Aim to keep pH stable in the shared range.

Next steps

Concrete changes, not "research more" filler.

  • Provide plenty of hiding spots and visual breaks so Green neon tetra can escape if harassed.
  • Green neon tetra should be kept in a group of at least 8 for best health and behaviour.

  • Provide plenty of hiding spots and visual breaks so Green neon tetra can escape if harassed.
  • Green neon tetra should be kept in a group of at least 8 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.
