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. 7 fish across 2 species in 160L. Shared temperature 24–28°C. Stocking: near-limit (load index 165 vs ref 160). 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.
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 160L tank is below that. Shop size is not adult size.
- African Cichlid + Agassiz’s dwarf cichlid: African Cichlid + Agassiz’s dwarf cichlid: Incompatible pH requirements. African Cichlid prefers pH 7.8–9 and Agassiz’s dwarf cichlid prefers pH 5–6.5. Their ranges do not overlap. Real tanks add variables Fishori cannot model; treat this as a high-risk read, not certainty.
Warnings
- pH preferences do not all overlap — some fish may sit at the edge of tolerance unless you target a compromise value carefully.
- Multiple bottom-oriented territorial species (African Cichlid, Agassiz’s dwarf cichlid) in 160L — expect turf fights unless the footprint is very long with many territories.
Water overlap
What every fish can share at the same time
Shared temperature: 24–28°C
pH ranges do not fully overlap — target a compromise carefully.
Shared temperature range for all species: 24–28°C.
Stocking pressure
near limit
Load index 165 vs conservative reference 160 for 160L (adult cm × quantity × bioload weight × territory factor).
Swim-zone distribution
Fish-weighted zone use — top 0.0, middle 3.5, bottom 3.5 (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: avoid
critical· other- African Cichlid + Agassiz’s dwarf cichlid: African Cichlid + Agassiz’s dwarf cichlid: Incompatible pH requirements. African Cichlid prefers pH 7.8–9 and Agassiz’s dwarf cichlid prefers pH 5–6.5. Their ranges do not overlap. Real tanks add variables Fishori cannot model; treat this as a high-risk read, not certainty.
Temperament gap
warning· temperament- African Cichlid (aggressive) and Agassiz’s dwarf cichlid (semi-aggressive) — needs space, line-of-sight breaks, and observation.
Bottom territory overlap
warning· aggression- African Cichlid + Agassiz’s dwarf cichlid: overlapping territory claims on the substrate.

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.
Behaviour & stress
Bottom territory focus: African Cichlid, Agassiz’s dwarf cichlid.
Fish behaviour varies. Fishori gives conservative planning guidance based on adult size, temperament, tank size and common aquarium care sources.
