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
Tank volume is below published minima for at least one species — shop size is not adult swimming space. Review supporting points next, then re-run the check.
Primary issue: Tank volume is below published minima for at least one species — shop size is not adult swimming space. Hard conflicts on file (water, pairing, size, or bettas) — resolve red items before fine-tuning decor or food. 20 fish across 3 species in 100L. Shared temperature 24–26°C. Stocking: overstocked (load index 180 vs ref 100). 2 high-severity pairing flag(s).
Your stock
Tank volume is below published minima for at least one species — shop size is not adult swimming space. Review supporting points next, then re-run the check.
Overstocked for this volume
Load index 180 vs conservative reference 100 for 100L (adult cm × quantity × bioload weight × territory factor).
One or more species profiles are only partially verified or need verification — treat numbers as planning guidance, not guarantees. At least one species has ID or trade-name ambiguity on file — plan for a typical trade example, not every shop label. Elevated risk verdict — we bias toward safety; your reading of specialist sources still matters.

Critical problems
- Boesemani Rainbowfish needs about 150L minimum for adult size (~11cm) and normal swimming space — your 100L tank is below that. Shop size is not adult size.
- Boesemani Rainbowfish + Harlequin Rasbora: Boesemani Rainbowfish + Harlequin Rasbora: Tank may be too small. Boesemani Rainbowfish and Harlequin Rasbora together need at least 150 litres. Your tank is 100 litres. Real tanks add variables Fishori cannot model; treat this as a high-risk read, not certainty.
- Boesemani Rainbowfish + Corydoras Catfish: Boesemani Rainbowfish + Corydoras Catfish: Tank may be too small. Boesemani Rainbowfish and Corydoras Catfish together need at least 150 litres. Your tank is 100 litres. Real tanks add variables Fishori cannot model; treat this as a high-risk read, not certainty.
Warnings
- Temperature overlap is narrow (24–26°C) — heater thermostat accuracy matters.
- 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: 24–26°C (narrow band)
Shared pH: 7.0–7.5 (tight overlap)
Shared temperature range for all species: 24–26°C.
Shared pH window: 7.0–7.5.
Stocking pressure
overstocked
Load index 180 vs conservative reference 100 for 100L (adult cm × quantity × bioload weight × territory factor).
Oscar, common pleco, large cichlids, and adult clown loaches raise the index sharply — not just length of fish.
Swim-zone distribution
Fish-weighted zone use — top 3.0, middle 11.0, bottom 6.0 (relative biomass per level).
Fish are spread across top, middle, and bottom zones reasonably for a community layout.

Activity / stress mismatch
warning· activity stress- Boesemani Rainbowfish (high activity) with Corydoras Catfish (low activity) — fast fish can outcompete at feeding time and cause chronic stress.

Fix this setup
Grouped by scenario — work through each block in order
Volume & minimum tank
- 1.Increase tank size to at least 150L, or remove Boesemani Rainbowfish from this stocking plan.
Species pairing & temperament
- 1.Clear each unsafe species pair by removing or replacing one side — do not stock while red compatibility flags remain.
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.
- Where a pleco is the volume problem, consider bristlenose pleco instead of common pleco for sub-200L plans.
Beginner difficulty
advanced
- Includes intermediate species — stable parameters matter.
- Serious compatibility or tank-size issues — not a beginner layout until resolved.
Behaviour & stress
Boesemani Rainbowfish (high activity) with Corydoras Catfish (low activity) — fast fish can outcompete at feeding time and cause chronic stress.
Fish behaviour varies. Fishori gives conservative planning guidance based on adult size, temperament, tank size and common aquarium care sources.
