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. 12 fish across 2 species in 100L. Shared temperature 24–26°C. Stocking: overstocked (load index 189 vs ref 100). 1 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 189 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
- African Cichlid needs about 200L minimum for adult size (~15cm) and normal swimming space — your 100L tank is below that. Shop size is not adult size.
- Adolfoi cory + African Cichlid: Adolfoi cory + African Cichlid: Tank may be too small. Adolfoi cory and African Cichlid together need at least 200 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 preferences do not all overlap — some fish may sit at the edge of tolerance unless you target a compromise value carefully.
Water overlap
What every fish can share at the same time
Shared temperature: 24–26°C (narrow band)
pH ranges do not fully overlap — target a compromise carefully.
Shared temperature range for all species: 24–26°C.
Stocking pressure
overstocked
Load index 189 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 0.0, middle 3.0, bottom 9.0 (relative biomass per level).
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
Volume & minimum tank
- 1.Increase tank size to at least 200L, or remove African Cichlid 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.
- Aggressive species require confident husbandry.
Fish behaviour varies. Fishori gives conservative planning guidance based on adult size, temperament, tank size and common aquarium care sources.
