Compatibility brief
Can Angelfish live with Celestial Pearl Danio?
Risky. This mix is commonly discouraged for typical setups.
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 Celestial Pearl Danio (~2.5cm) as food once grown — plan adult sizes, not shop sizes.
Temperament gap (semi-aggressive vs peaceful) adds stress on top of the hard incompatibility — space and cover do not make this pairing safe.
Assessment details
Temperament difference
Angelfish is semi-aggressive, while Celestial Pearl Danio is peaceful. Expect chasing or stress unless the tank is large and heavily structured — monitor closely.
Angelfish may eat Celestial Pearl Danio

Narrow temperature overlap
Angelfish and Celestial Pearl Danio have only a narrow shared temperature range. Maintaining stable water temperature will be important.

Next steps
Concrete changes, not "research more" filler.
- •Provide plenty of hiding spots and visual breaks so Celestial Pearl Danio can escape if harassed.
- •Celestial Pearl Danio should be kept in a group of at least 8 for best health and behaviour.
Try instead
- →Build a species-only tank for the larger fish, or restock with fish too large to be eaten at adult sizes.

Plan further
Check each species’ mates list, size the glass, then verify the full stock in the builder. 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. Checked against several solid care sources that mostly agree.
