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 · RISKY
Schooling welfare — a shoaling species is below the safe minimum group size. Review supporting points next, then re-run the check.
Primary issue: Schooling welfare — a shoaling species is below the safe minimum group size. Hard conflicts on file (water, pairing, size, or bettas) — resolve red items before fine-tuning decor or food. 8 fish across 3 species in 200L. Shared temperature 24–28°C. Stocking: balanced (load index 98 vs ref 200).

One or more species profiles are only partially verified or need verification — treat numbers as planning guidance, not guarantees. Elevated risk verdict — we bias toward safety; your reading of specialist sources still matters.

Critical problems
- Boesemani Rainbowfish is a schooling/shoaling species — keeping only 1 is a serious welfare risk; aim for at least 6.
Warnings
- pH overlap is tight — large water changes can swing chemistry outside the safe band.
Water overlap
What every fish can share at the same time
Shared temperature: 24–28°C
Shared pH: 7.0–7.5 (tight overlap)
Shared temperature range for all species: 24–28°C.
Shared pH window: 7.0–7.5.
Stocking pressure
balanced
Load index 98 vs conservative reference 200 for 200L (adult cm × quantity × bioload weight × territory factor).
Swim-zone distribution
Fish-weighted zone use — top 4.0, middle 4.0, bottom 0.0 (relative biomass per level).
Most biomass leans toward one swim level — shy fish may feel exposed or outcompeted at feeding time.
Compatibility summary
Species pairing: needs care
warning· other- Boesemani Rainbowfish + Dwarf Gourami: Boesemani Rainbowfish + Dwarf Gourami: Hardness preference mismatch. Boesemani Rainbowfish prefers hard water and Dwarf Gourami prefers soft water. One of them lives outside its comfort band long-term — pick the tank's water for the more sensitive species. Outcomes still depend on your tank shape, maintenance routine, and individual fish.

Fix this setup
Grouped by scenario — work through each block in order
Schooling & group sizes
- 1.Add more Boesemani Rainbowfish to reach at least 6 individuals, or remove the species.
Layout & swim zones
- 1.Add structure (caves, tall plants) and consider species that use under-represented zones.
Suggested swaps
- Single-biome community: e.g. soft-water South Americans together (tetras + corydoras + small gourami) — run the pair tool for every add-on.
- Species or centrepiece tank: one main species (or one compatible pair group) in a right-sized aquarium with dither fish from the same water profile — not random continent mixing.
Beginner difficulty
advanced
- Includes intermediate species — stable parameters matter.
- Serious compatibility or tank-size issues — not a beginner layout until resolved.
Schooling / group size
- Boesemani Rainbowfish is a schooling/shoaling species — keeping only 1 is a serious welfare risk; aim for at least 6.
