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
Predation risk dominates — at least one adult fish is likely to eat or badly injure a smaller tank mate once grown. Review supporting points next, then re-run the check.
Primary issue: Predation risk dominates — at least one adult fish is likely to eat or badly injure a smaller tank mate once grown. Hard conflicts on file (water, pairing, size, or bettas) — resolve red items before fine-tuning decor or food. Shared temperature can still exist on paper — that does not cancel adult predation risk once fish grow into their mouths. 8 fish across 3 species in 100L. Shared temperature 20–26°C. Stocking: near-limit (load index 109 vs ref 100). 2 high-severity pairing flag(s).
