Planning verdict
incompatibleDo not plan a shared aquarium for this pair. Choose a different tank mate or maintain separate aquariums.
Malaysian Trumpet Snail and Rainbow Shark receive a not recommended verdict from the current structured assessment. Malaysian Trumpet Snail is recorded as peaceful with an aggression level of 1/10; Rainbow Shark is recorded as semi-aggressive with an aggression level of 5/10. The recommendation is based on the combined water, space, behavior, grouping, and predation checks below rather than on species names alone.
Malaysian Trumpet Snail has a recorded temperature range of 68–82°F and pH range of 7–8.5. Rainbow Shark is recorded at 72–82°F and pH 6.5–7.5. Their shared planning window is 72–82°F for temperature and 7–7.5 for pH. A shared aquarium must stay inside the overlap rather than merely touching each species’ outer tolerance.
Rainbow Shark sets the larger listed base aquarium requirement at 55 gallons; the other listed minimum is 5 gallons. Rainbow Shark 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.
Malaysian Trumpet Snail is a moderate species associated with the bottom zone and moderate flow. Rainbow Shark is moderate, uses the bottom zone, and has a moderate flow preference. Malaysian Trumpet Snail does not have a recorded minimum school larger than one, while rainbow shark does not have a recorded minimum school larger than one. The aquarium must support both social structures without forcing either species into insufficient space.
Malaysian Trumpet Snail is recorded as a omnivore with easy care, while Rainbow Shark 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.
