How TankStockPlan calculates your result
Review water ranges, group sizes, tank dimensions, and unresolved behavior constraints. No opaque stocking score. No false compatibility guarantee.
Start with evidence, not a score
Estimate actual water volume from internal dimensions, fill height, and displacement, not the nominal tank label. Check each species against entered adult-space requirements, minimum social group, and measured water ranges.
Read the assumptions
Keep cycle status, aggression, missing husbandry evidence, and other uncertainty visible. Passing numeric checks never becomes a guaranteed compatibility score. Prioritize animal welfare. A specialist-reviewed husbandry plan and a properly cycled, stable aquarium are required; this calculator is not approval to add fish.
Use a reproducible workflow
Enter your own measurements or import records using the published CSV schema. Save a local scenario before making a change, compare the result, and export a copy with the assumptions intact. Example inputs are not a verified catalog or a live data feed. The source references explain the underlying terminology; they do not independently verify information you enter.
