Can Angelfish Live With Molly?
Maybe, with caveats -- mollies are active and may nip angelfish fins, but size and temperament decide the outcome.
Why
- Angelfish grow to 6 inches tall and have long flowing fins that attract attention from active tankmates.
- Mollies reach 4 to 5 inches and are fast swimmers with a reputation for fin-nipping at slow-moving fish.
- Both species tolerate overlapping temperatures (76-82F) and pH (7.0-7.5), so water conditions are not the barrier.
- A 30-gallon minimum gives angelfish room to establish territory and reduces collision points with molly schools.
What could go wrong
Mollies may target angelfish fins, especially as angelfish grow larger and slower, leading to torn fins and stress.
Gear for a shared tank
Sized for the 30 gallon minimum this pairing needs. Affiliate links — we earn a small commission if you buy through them.
AquaClear 70 Power Filter
Oversized filtration is what lets you stock two species together without water quality crashing. Rated for a tank slightly larger than the 30 gallon minimum.
Eheim Jager 200W Thermostat Heater
Holds a steady temperature inside the 76-82°F window both species need.
API Freshwater Master Test Kit
Keep ammonia, nitrite, and nitrate in check. Two-species tanks have more bioload and less margin for error than single-species setups.
Better pairings to consider
Angelfish do better with peaceful tetras or corydoras; mollies do well with platies or swordtails.
