Caution. Check the issues below before buying.

Angelfish + Guppy: Temperament difference. Angelfish is semi-aggressive, while Guppy is peaceful. Expect chasing or stress unless the tank is large and heavily structured — monitor closely. Outcomes still depend on your tank shape, maintenance routine, and individual fish.

Size / predation

Angelfish (20cm adult) may treat small Guppy (~5cm) as food once grown — plan adult sizes, not shop sizes.

Temperament / behaviour

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

Angelfish + Guppy — common questions

Can Angelfish live with Guppy?
Yes, if you plan for it. The verdict is CAUTION, which means the pairing works when specific conditions are met, not by default. The first condition: Provide plenty of hiding spots and visual breaks so Guppy can escape if harassed.
What tank size do you need for Angelfish and Guppy together?
Plan around 150 litres as the working minimum. That figure comes from each species' published minimum and their group needs, and it assumes adult sizes, not shop sizes.
What's the main risk?
Temperament difference. That is the first thing to plan around. The matching entry under assessment details on this page explains the reasoning and the numbers behind it.
