Stocking plan

Plan a freshwater tank stocking

Set volume, add species with the numbers you actually plan to keep, and get a conservative verdict for the whole stocking — bioload, group size, zone crowding, and multi-species conflicts, not a single pair in isolation. Use the editor first; the planning notes below explain why a pairwise match still needs a tank-level check.

Shared plan · CAUTION

Group sizes are under hobby norms for at least one social species — behaviour and stress follow group size. Review supporting points next, then re-run the check.

Primary issue: Group sizes are under hobby norms for at least one social species — behaviour and stress follow group size. Reads as a general community basket — outcome depends on honest volume, peaceful choices, and filtration headroom. 2 fish across 2 species in 150L. Shared temperature 22–28°C. Stocking: understocked (load index 38 vs ref 150).
