No automatic safety blocker was found.
Silver Dollar and Wrestling Halfbeak receive a conditional verdict from the current structured assessment. Silver Dollar is recorded as peaceful with an aggression level of 2/10; Wrestling Halfbeak is recorded as semi-aggressive with an aggression level of 4/10. The recommendation is based on the combined water, space, behavior, grouping, and predation checks below rather than on species names alone.
Silver Dollar has a recorded temperature range of 75–82°F and pH range of 5–7. Wrestling Halfbeak is recorded at 75–82°F and pH 6.5–8. Their shared planning window is 75–82°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.
Silver Dollar sets the larger listed base aquarium requirement at 75 gallons; the other listed minimum is 20 gallons. Silver Dollar is the larger adult by the recorded maximum, reaching 6 inches, compared with 3 inches. These figures are starting constraints, not a stocking-capacity calculation, because the complete group sizes and bioload still matter.
Silver Dollar is a active species associated with the mid zone and moderate flow. Wrestling Halfbeak is calm, uses the top zone, and has a moderate flow preference. Silver Dollar should be planned as a group of at least 6, while wrestling halfbeak should be planned as a group of at least 4. The aquarium must support both social structures without forcing either species into insufficient space.
Silver Dollar is recorded as a herbivore with intermediate care, while Wrestling Halfbeak is a carnivore with advanced care. Their listed preferred tank styles are community 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.
Use these pair-specific boundaries before treating the verdict as an acceptable stocking plan.
