Can Albino Pleco Live With Molly?
Yes, albino plecos and mollies share a 30-gallon tank comfortably, with the pleco on the bottom and mollies in the upper levels.
Why
- Albino plecos are 5-inch bottom dwellers while mollies are 4-5 inch top-level swimmers, so they use completely different tank zones.
- Temperature overlap spans 72-82°F and pH overlap is 7.0-7.5, a range both species handle well.
- Mollies are diurnal and active during the day while plecos rest in caves during daylight hours, minimizing interaction.
- Both species prefer similar water hardness and alkalinity levels.
What could go wrong
The pleco may graze on algae and biofilm before the mollies notice, which is beneficial rather than problematic for the tank.
