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. 7 fish across 2 species in 180L. Shared temperature 24–28°C. Stocking: near-limit (load index 167 vs ref 180).

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.

Pair compatibility for any two species · Fish library

Critical problems

  • Boesemani Rainbowfish is a schooling/shoaling species — keeping only 1 is a serious welfare risk; aim for at least 6.

Warnings

  • Stocking is approaching the practical limit for 180L (load index 167 / ref 180).

Water overlap

What every fish can share at the same time

Shared temperature: 2428°C

Shared pH: 7.08.0

Shared temperature range for all species: 24–28°C.

Shared pH window: 7.0–8.0.

Stocking pressure

near limit

Load index 167 vs conservative reference 180 for 180L (adult cm × quantity × bioload weight × territory factor).

Swim-zone distribution

Fish-weighted zone use — top 0.5, middle 6.5, bottom 0.0 (relative biomass per level).

top 1
middle 7
bottom 0

Most biomass leans toward one swim level — shy fish may feel exposed or outcompeted at feeding time.

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.

Stocking pressure & filtration

  • 1.Avoid adding more large or messy fish; keep a strict maintenance schedule.

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.
  • Stocking is heavy for the volume — needs reliable filtration and a steady water-change routine.

Schooling / group size

  • Boesemani Rainbowfish is a schooling/shoaling species — keeping only 1 is a serious welfare risk; aim for at least 6.
