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. Temperament spread or predators in the mix — feeding order, territory, and observation matter more than in an all-peaceful list. 10 fish across 3 species in 60L. Shared temperature 24–28°C. Stocking: balanced (load index 38 vs ref 60).

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 (24–28°C).
- StockingEvery listed species has a published minimum tank size at or below 60L.

What every fish can share at the same time
Shared temperature: 24–28°C
Shared pH: 6.5–7.0 (tight overlap)
Shared temperature range for all species: 24–28°C.

Stocking pressure
balanced
Load index 38 vs conservative reference 60 for 60L (adult cm × quantity × bioload weight × territory factor).
Swim-zone distribution
Fish-weighted zone use — top 3.5, middle 5.0, bottom 1.5 (relative biomass per level).
Fish are spread across top, middle, and bottom zones reasonably for a community layout.
Compatibility summary
Species pairing: needs care
warning· other- Amano Shrimp + Beckford Pencilfish: Amano Shrimp and Beckford Pencilfish: 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.
- Amano Shrimp + Betta: Amano Shrimp + Betta: Caution advised. Bettas tolerate amanos better than cherries because the larger shrimp do not look like food. Some bettas still hunt them. Plant heavily, add the shrimp first, and expect at least one loss before the betta settles. Outcomes still depend on your tank shape, maintenance routine, and individual fish.
- Beckford Pencilfish + Betta: Beckford Pencilfish + Betta: Temperament difference. Betta is semi-aggressive, while Beckford Pencilfish is peaceful. Expect chasing or stress unless the tank is large and heavily structured — monitor closely. Outcomes still depend on your tank shape, maintenance routine, and individual fish.
Temperament gap
warning· temperament- Amano Shrimp (peaceful) and Betta (semi-aggressive) — needs space, line-of-sight breaks, and observation.

Fix this setup
Grouped by scenario — work through each block in order
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
- Several caution flags — needs experience reading fish behaviour.
Behaviour & stress
With Amano Shrimp: watch for fin damage or chasing; keep a backup plan if aggression appears.
With Beckford Pencilfish: watch for fin damage or chasing; keep a backup plan if aggression appears.
Fish behaviour varies. Fishori gives conservative planning guidance based on adult size, temperament, tank size and common aquarium care sources.
