VerdictCAUTION

Caution. Check the issues below before buying.

Angelfish + Platy: Caution advised. Platys are peaceful surface-to-mid fish that do fine chemically with many community tanks, but adult angels treat them as slow neighbours and occasional snacks once gape catches up. Keep platys with quieter tank mates unless the angels stayed small. Outcomes still depend on your tank shape, maintenance routine, and individual fish.

Size / predation

Angelfish (20cm adult) may treat small Platy (~6cm) 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.
