AngelfishVSMolly Fish

Can they live together? Complete Compatibility Analysis

Compatibility Score
75
⚠️ 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.
