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 · CAUTION

Temperature overlap is razor-thin — small heater drift or a cold room swings someone out of range. Review supporting points next, then re-run the check.

Primary issue: Temperature overlap is razor-thin — small heater drift or a cold room swings someone out of range. Reads as a general community basket — outcome depends on honest volume, peaceful choices, and filtration headroom. 15 fish across 3 species in 80L. Shared temperature 24–26°C. Stocking: near-limit (load index 84 vs ref 80).

At least one species has ID or trade-name ambiguity on file — plan for a typical trade example, not every shop label.

Warnings

  • Temperature overlap is narrow (24–26°C) — heater thermostat accuracy matters.
  • Stocking is approaching the practical limit for 80L (load index 84 / ref 80).

Positives

  • CommunityPeaceful community core — no aggressive species in the list.
  • StockingEvery listed species has a published minimum tank size at or below 80L.

Water overlap

What every fish can share at the same time

Shared temperature: 2426°C (narrow band)

Shared pH: 6.07.5

Shared temperature range for all species: 24–26°C.

Swim-zone distribution

Fish-weighted zone use — top 0.5, middle 6.5, 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
  • Corydoras Catfish + Honey Gourami: Corydoras Catfish + Honey Gourami: Narrow temperature overlap. Corydoras Catfish and Honey Gourami have only a narrow shared temperature range. Maintaining stable water temperature will be important. Outcomes still depend on your tank shape, maintenance routine, and individual fish.

Pairs checked: 3 · RISKY pair flags: 0 · CAUTION: 1

Fix this setup

Grouped by scenario — work through each block in order

Stocking pressure & filtration

  • 1.Avoid adding more large or messy fish; keep a strict maintenance schedule.

Layout & swim zones

  • 1.Add structure (caves, tall plants) and consider species that use under-represented zones.

Beginner difficulty

moderate

  • Several caution flags — needs experience reading fish behaviour.
  • Stocking is heavy for the volume — needs reliable filtration and a steady water-change routine.

Fish behaviour varies. Fishori gives conservative planning guidance based on adult size, temperament, tank size and common aquarium care sources.
