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.

Biomass vs volume — stocking pressure is too high for this tank size and typical filtration. Review supporting points next, then re-run the check.
Primary issue: Biomass vs volume — stocking pressure is too high for this tank size and typical filtration. Biomass is tight for the litre count — plan filtration, water changes, and future growth like equipment, not luck. 7 fish across 2 species in 400L. Shared temperature 24–28°C. Stocking: overstocked (load index 539 vs ref 400).
