Best angelfish (angel fish) tank mates

General compatibility rules

Choose medium-sized, peaceful-to-semi-peaceful fish that are not tiny enough to be eaten and not aggressive enough to harass angelfish. Bigger tanks reduce territorial conflict.

Tank mates that often work

• Corydoras: peaceful bottom dwellers in groups.
• Larger tetras: species that are not tiny or fin-nippy.
• Peaceful rainbowfish: in appropriately sized tanks.
• Plecos (small/peaceful species): with caution and proper tank size.

Species to avoid

• Fin-nippers (many barbs and aggressive tetras)
• Very small nano fish that may be seen as food
• Highly aggressive cichlids in undersized setups

Setup tips

Use line-of-sight breaks with plants/decor, provide vertical space, and avoid overstocking. Add fish gradually and watch behavior during the first weeks.

Quick takeaways

• Tank mates should be peaceful, not tiny, and not fin-nippy.
• More space and structure = fewer aggression issues.
• Always keep a backup plan if personalities clash.
