The short answer
Angelfish are peaceful for a cichlid but they are predators of small fish, so pick calm, medium-sized companions that can’t be eaten and won’t nip their long fins. In a tall tank of 200 litres or more, good choices are:
- Larger tetras like rummynose, lemon or black skirt tetras
- Corydoras and bristlenose plecos (peaceful bottom crew)
- Bolivian rams or pearl gouramis (calm mid-water fish)
- Congo tetras in a bigger tank
Two rules: too big to eat, too calm to nip
Angelfish problems come from two directions. First, anything smaller than their mouth is food — that means neon tetras, chili rasboras, ember tetras and dwarf shrimp are risky, even if it “works” for a while. Second, angelfish have long, trailing fins that fin-nippers can’t resist, so avoid tiger barbs, serpae tetras and other known nippers. Aim for the middle ground: fish that are a few centimetres long, unhurried, and uninterested in fins.
Give them height and stability
Angelfish grow tall and need a deep tank (45 cm / 18 inches or more) with tall plants or driftwood to feel secure. A pair may become territorial when breeding, so give the tank plenty of space and cover. Keep water warm and stable, and stock gradually to avoid overloading the filter.
Before adding a group, check how many fish you can keep and read our full angelfish care guide. For the tank itself, browse the aquariums hub. If you’re weighing up centrepiece options, see the best centrepiece fish for a community tank.
