Angelfish tank mates
A striking-looking cichlid for a tall 200L+ planted tank. Pairs claim a territory, and adults eat neon-sized fish, even ones they were raised with.
Lists below are built from this species record (safest, best with, risky, unsafe) — each link opens a pair-level check, not a guarantee.
Best tank mates (on file)
Merged from conservative safest and best with fields — de-duplicated by species.
The Angelfish profile lists Corydoras Catfish as both safe and a recommended pairing. Corydoras Catfish schools in groups of 6 or more, so plan room for the whole group rather than one fish. Corydoras Catfish grows to about 6cm, which is borderline mouth-size for an adult 20cm Angelfish. Corydoras Catfish swims in the bottom zone while Angelfish stays in the middle, so the two will not crowd the same water column.
The Angelfish profile lists German Blue Ram as both safe and a recommended pairing. German Blue Ram grows to about 7cm, which is borderline mouth-size for an adult 20cm Angelfish.
The Angelfish profile lists Harlequin Rasbora as both safe and a recommended pairing. Harlequin Rasbora schools in groups of 6 or more, so plan room for the whole group rather than one fish. Harlequin Rasbora grows to about 5cm, which is borderline mouth-size for an adult 20cm Angelfish.
The Angelfish profile lists Pearl Gourami as both safe and a recommended pairing. Pearl Gourami is a peaceful beginner-care species with a 100L minimum. Run the pair checker for your specific tank before stocking.

Tank size and groups
- Published minimum for Angelfish: 150L — group minimum 1 .
- Compatibility changes when the tank is too short for turning, too little for a real school, or too warm for one species and not the other — that is why pair checks include tank context, not only temperament.
- Nearest litre hub to this minimum: 160L hub.
Easier alternatives to consider
Conservative beginner-peaceful picks from the library — not replacements for reading, but a shorter on-ramp than this species for a first tank.
Plan before you buy
Pair checks for every mix, then multi-species stocking in the builder.
