Can Convict Cichlid Live With Jack Dempsey?
Yes, convict cichlids and Jack Dempseys coexist in 55 gallons or larger because both are New World cichlids with matching temperature and pH requirements.
Why
- Both species thrive in the same temperature range of 75-82°F, so no heater adjustments are needed.
- The pH overlap of 6.5-8 covers slightly acidic to alkaline water that suits both cichlids.
- Convict cichlids and Jack Dempseys are similarly sized as adults, reducing the risk of one eating the other.
- Both species prefer similar hiding spots among rocks and driftwood, which simplifies tank decoration.
- A 55-gallon tank gives each fish enough space to establish its own territory without constant conflict.
What could go wrong
Territorial disputes may escalate during breeding periods when both fish defend caves and substrate aggressively.
