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.

Behaviour stack — multiple caution-level pairs or activity mismatches make outcomes harder to predict than a simple community mix. Review supporting points next, then re-run the check.
Primary issue: Behaviour stack — multiple caution-level pairs or activity mismatches make outcomes harder to predict than a simple community mix. Reads as a general community basket — outcome depends on honest volume, peaceful choices, and filtration headroom. 10 fish across 3 species in 300L. Shared temperature 22–26°C. Stocking: understocked (load index 54 vs ref 300).

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. Several caution-level pair flags mean real outcomes depend on tank shape, cover, and individual fish. Elevated risk verdict — we bias toward safety; your reading of specialist sources still matters.

Warnings
- pH overlap is tight — large water changes can swing chemistry outside the safe band.
Positives
- WaterTemperature ranges overlap comfortably (22–26°C).
- StockingStocking pressure looks conservative — room to grow schools or add compatible species if filtration allows.
- StockingEvery listed species has a published minimum tank size at or below 300L.
Water overlap
What every fish can share at the same time
Shared temperature: 22–26°C
Shared pH: 6.5–6.5 (tight overlap)
Shared temperature range for all species: 22–26°C.
Shared pH window: 6.5–6.5.
Stocking pressure
understocked
Load index 54 vs conservative reference 300 for 300L (adult cm × quantity × bioload weight × territory factor).
Swim-zone distribution
Fish-weighted zone use — top 0.0, middle 2.0, bottom 8.0 (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- Adolfoi cory + Amano Shrimp: Adolfoi cory + Amano Shrimp: Narrow pH overlap. These fish can share water but their ideal pH ranges overlap only slightly. Aim to keep pH stable in the shared range. Outcomes still depend on your tank shape, maintenance routine, and individual fish.
- Adolfoi cory + Bamboo Shrimp: Adolfoi cory + Bamboo Shrimp: Narrow pH overlap. These fish can share water but their ideal pH ranges overlap only slightly. Aim to keep pH stable in the shared range. Outcomes still depend on your tank shape, maintenance routine, and individual fish.
- Amano Shrimp + Bamboo Shrimp: Amano Shrimp and Bamboo Shrimp: ID ambiguity and thin sources on at least one side, so this is a cautious read, not a green light. Plan for adult sizes, a stable shared water window, and individual behaviour; verify against a second reference you trust.

Fix this setup
Grouped by scenario — work through each block in order
Layout & swim zones
- 1.Add structure (caves, tall plants) and consider species that use under-represented zones.
Overall plan
- 1.Choose one direction: remove the highest-risk species first, or change the tank class (length, volume, filtration) to match the adults you intend to keep — halfway plans fail most often here.
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
moderate
- Includes intermediate species — stable parameters matter.
- Several caution flags — needs experience reading fish behaviour.
Fish behaviour varies. Fishori gives conservative planning guidance based on adult size, temperament, tank size and common aquarium care sources.
