Clown Killifish and Siamese Algae Eater receive a recommended verdict from the current structured assessment. Clown Killifish is recorded as peaceful with an aggression level of 1/10; Siamese Algae Eater 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.
Clown Killifish has a recorded temperature range of 68–79°F and pH range of 5–7. Siamese Algae Eater is recorded at 75–79°F and pH 6.5–8. Their shared planning window is 75–79°F for temperature and 6.5–7 for pH. A shared aquarium must stay inside the overlap rather than merely touching each species’ outer tolerance.
Siamese Algae Eater sets the larger listed base aquarium requirement at 30 gallons; the other listed minimum is 5 gallons. Siamese Algae Eater is the larger adult by the recorded maximum, reaching 6 inches, compared with 1.4 inches. These figures are starting constraints, not a stocking-capacity calculation, because the complete group sizes and bioload still matter.
Clown Killifish is a calm species associated with the top zone and moderate flow. Siamese Algae Eater is active, uses the bottom zone, and has a high flow preference. Clown Killifish should be planned as a group of at least 6, while siamese algae eater does not have a recorded minimum school larger than one. The aquarium must support both social structures without forcing either species into insufficient space.
Clown Killifish is recorded as a carnivore with intermediate care, while Siamese Algae Eater is a herbivore with easy 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.
