Possible, but with meaningful cautions
Their pH overlap is narrow.
Practical response: Confirm your stable source-water pH sits within the shared range.

Water parameter overlap
Behavior and space
A comparatively large, high-output livebearer needing space, hard water and robust filtration. Tall-bodied cichlids that need vertical room and may prey on very small fish as they mature.
A compatibility answer should also consider the actual tank dimensions, number of each fish, filtration, planting and other occupants. Two species can be reasonable together in a long, structured aquarium yet become a poor pairing when compressed into a small footprint.
Common questions
Can Molly live with Angelfish?
The StockingLab verdict is caution: Their pH overlap is narrow.
Do their temperatures overlap?
24–28°C / 75.2–82.4°F shared range.
Should I trust compatibility calculators completely?
No. Individual behavior, sex ratios, breeding condition, aquascape and tank size can change the outcome. Use the result to identify risks, then verify care requirements before purchase.
