Generally compatible on core signals
No major temperature, pH, size or behavioural conflict is flagged by the planning model.
Practical response: Still observe individual behaviour and verify species-specific care before purchase.

Water parameter overlap
Behavior and space
Tall-bodied cichlids that need vertical room and may prey on very small fish as they mature. A warm-water dwarf cichlid that needs stable conditions and may defend a breeding territory.
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 Angelfish live with German Blue Ram?
The StockingLab verdict is good: No major temperature, pH, size or behavioural conflict is flagged by the planning model.
Do their temperatures overlap?
26–30°C / 78.8–86°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.
