Planning verdict
incompatibleDo not plan a shared aquarium for this pair. Choose a different tank mate or maintain separate aquariums.
Bloodfin Tetra and Convict Cichlid receive a not recommended verdict from the current structured assessment. Bloodfin Tetra is recorded as peaceful with an aggression level of 2/10; Convict Cichlid is recorded as aggressive with an aggression level of 8/10. The recommendation is based on the combined water, space, behavior, grouping, and predation checks below rather than on species names alone.
Bloodfin Tetra has a recorded temperature range of 64–82°F and pH range of 6–8. Convict Cichlid is recorded at 75–82°F and pH 6.6–7.8. Their shared planning window is 75–82°F for temperature and 6.6–7.8 for pH. A shared aquarium must stay inside the overlap rather than merely touching each species’ outer tolerance.
Convict Cichlid sets the larger listed base aquarium requirement at 30 gallons; the other listed minimum is 20 gallons. Convict Cichlid is the larger adult by the recorded maximum, reaching 6 inches, compared with 2.2 inches. These figures are starting constraints, not a stocking-capacity calculation, because the complete group sizes and bioload still matter.
Bloodfin Tetra is a active species associated with the mid zone and moderate flow. Convict Cichlid is moderate, uses the cave zone, and has a moderate flow preference. Bloodfin Tetra should be planned as a group of at least 6, while convict cichlid should be planned as a group of at least 2. The aquarium must support both social structures without forcing either species into insufficient space.
Bloodfin Tetra is recorded as a omnivore with easy care, while Convict Cichlid is a omnivore with intermediate care. Their listed preferred tank styles are planted and rockwork. Feeding access, cover, open swimming room, filtration, and observation should be planned around the more demanding requirement rather than averaged between the two species.
Use these pair-specific boundaries before treating the verdict as an acceptable stocking plan.
