⚠️ Caution

Angelfish and Mollies can coexist in a large, well-planted tank with careful management. Their water parameter and temperature ranges overlap sufficiently. However, adult Angelfish are semi-aggressive cichlids and may view small or fancy-finned Mollies as food or targets for fin-nipping, especially during breeding. Mollies are generally peaceful but can be boisterous, which may stress shy Angelfish.

Potential Issues

•Adult Angelfish may prey on small or juvenile Mollies.
•Angelfish may nip the fins of fancy Mollies (e.g., Sailfin).
•Mollies prefer harder, more alkaline water than the ideal for Angelfish; a middle-ground must be found.

Tank Requirements

Temperature

75-80°F (24-27°C) - A compromise within both species' ranges.

pH Level

7.0-7.8 - Aim for the middle; Mollies prefer the higher end, Angelfish the lower.

Minimum Tank Size

30 gallons (113 liters) minimum, with 55 gallons (208 liters) being ideal to reduce aggression and territoriality.
