* Different Water Parameters: Convict fish prefer slightly cooler water temperatures (72-82°F) and a lower pH than most African cichlids. Mixing them can lead to health problems for one or both species.
* Aggression: Both convict fish and African cichlids can be aggressive, especially during breeding season. They might fight over territory, food, or even mating partners.
* Diet: While both are omnivores, their dietary needs can differ. Convicts typically eat more insects and crustaceans, while African cichlids favor algae and plant matter.
* Tank Size: Convict fish and African cichlids can both grow quite large. You'll need a spacious tank (at least 75 gallons) to comfortably house them together, which may be impractical.
Potential Problems:
* Stress and Disease: If the water conditions aren't optimal for both species, they can become stressed and more susceptible to diseases.
* Injuries: Fighting can lead to serious injuries, even death.
* Breeding Issues: Convicts can be aggressive towards other fish while breeding, potentially harming African cichlids.
Alternatives:
* Keep them separate: It's the safest and most practical option. Create separate tanks with the proper water conditions for each species.
* Choose compatible cichlids: There are some South American cichlids that could coexist with convict fish, such as firemouths (Thorichthys meeki) or green terrors (Andinoacara rivulatus).
Before making any decisions, carefully research the specific needs of the fish you are considering. Consult with a knowledgeable fishkeeper or veterinarian if you have doubts.
