Jump to next section Husbandry Information
Feeding Not a fussy eater and will take all manner of prepared and live foods. Will eat smaller tankmates.
Furniture Some driftwood/rocks/pipes as hiding spaces.
Compatibility Should only be housed with large, robust fish (large central American cichlids are ideal), as smaller tankmates will be eaten. Territorial and aggressive towards conspecifics.
Suggested Tankmates Large, robust fish (such as central American cichlids).
Breeding Not reported in aquarium, but bred for aquaculture as food fish. Non-adhesive demersal eggs (1.1 to 2.8 mm diameter) are laid down, hatching after about 48 hours at 22°C. Ten days later, the larvae weigh approximately 100 mg but growth is slow (0.5 to 1.15 g per day).
