Cockatoo Cichlid and Peacock Gudgeon receive a conditional verdict from the current structured assessment. Cockatoo Cichlid is recorded as semi-aggressive with an aggression level of 4/10; Peacock Gudgeon is recorded as peaceful with an aggression level of 2/10. The recommendation is based on the combined water, space, behavior, grouping, and predation checks below rather than on species names alone.
Cockatoo Cichlid has a recorded temperature range of 75–82°F and pH range of 6–8. Peacock Gudgeon is recorded at 72–79°F and pH 6.5–7.8. Their shared planning window is 75–79°F for temperature and 6.5–7.8 for pH. A shared aquarium must stay inside the overlap rather than merely touching each species’ outer tolerance.
Cockatoo Cichlid sets the larger listed base aquarium requirement at 20 gallons; the other listed minimum is 15 gallons. Cockatoo Cichlid is the larger adult by the recorded maximum, reaching 3.2 inches, compared with 3 inches. These figures are starting constraints, not a stocking-capacity calculation, because the complete group sizes and bioload still matter.
Cockatoo Cichlid is a calm species associated with the cave zone and moderate flow. Peacock Gudgeon is moderate, uses the cave zone, and has a moderate flow preference. Cockatoo Cichlid should be planned as a group of at least 2, while peacock gudgeon should be planned as a group of at least 2. The aquarium must support both social structures without forcing either species into insufficient space.
Cockatoo Cichlid is recorded as a carnivore with intermediate care, while Peacock Gudgeon is a carnivore with intermediate care. Their listed preferred tank styles are blackwater and planted. Feeding access, cover, open swimming room, filtration, and observation should be planned around the more demanding requirement rather than averaged between the two species.
