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 · GOOD
On paper this can work — still match filtration, adult sizes, and run pair checks; real fish may surprise you.
Single-species or centrepiece lean — fewer cross-species surprises; match temperature and pH tightly to that fish. 5 fish across 1 species in 300L. Shared temperature 22–28°C. Stocking: balanced (load index 221 vs ref 300).

One or more species profiles are only partially verified or need verification — treat numbers as planning guidance, not guarantees.
