Methodology
How compatibility scores are calculated
Scores combine chemistry overlap, habitat fit, behaviour conflict, and predation evidence. Confidence is reduced whenever evidence shifts from exact records to inference.
- Temperature, pH, and hardness overlap are scored from published numeric ranges, combining FishBase stock water fields, official preferred-temperature quartiles, and exact SeriouslyFish water-condition pages where matched aquarium species exist.
- Aggression and territoriality use SeriouslyFish behaviour profiles and exact linked tankmate notes where a matched species page exists, including FishBase synonym matching for pages published under older names.
- FishBase ecology remarks also supply species-level territorial, aggression, and social-structure signals where exact aquarium behaviour pages are missing.
- Unmatched fish first inherit genus or family behaviour archetypes derived from matched high-evidence behaviour profiles, including synonym-linked genus clusters, before falling back to lower-confidence FishBase-derived behaviour signals.
- Predation risk uses direct FishBase food item records, FishBase reverse predator records, and FishBase synonym matching for exact predator-prey species pairs when available.
- SeaLifeBase reverse predator records add extra exact fish-on-invertebrate evidence for curated freshwater and brackish invertebrates mapped to SeaLifeBase species or synonym entries.
- GloBI literature-backed interaction records add extra exact prey matches across fish and curated invertebrates, while genus and family evidence remains available where exact prey records are under-resolved.
- When FishBase and GloBI do not show an exact pairwise prey record, predation falls back to a conservative inference from adult size, trophic level, and feeding profile.
- Search ranking favors aquarium-relevant species and stronger evidence coverage.
- Curated shrimp and invertebrate aquarium layers prioritize exact species evidence, then taxon-level GloBI prey records, before conservative fallback inference.
Why this planner works
A full compatibility matrix with transparent evidence
Use this planner to evaluate community fish, cichlids, shrimp colonies, and mixed invertebrate setups with clear, readable scoring rationale.
Exact pair evidence is always prioritized
The planner uses direct FishBase and literature-backed prey records first, then clearly labels any taxon-level evidence or inference.
658 direct prey linksAggression is evaluated separately from predation
Behaviour scoring combines matched species profiles with taxonomy-aware fallback so territorial conflict is visible even when feeding data looks neutral.
612 matched behaviour profilesMatrix and ranked pairs stay in sync
Review a full matrix, filter pair quality, and open detailed explanations without losing your current selection or focus species.

Compatibility FAQ
Compatibility questions, answered clearly
These answers explain how scoring works before you even run your first comparison.
How is this different from a generic fish compatibility chart?
Each selected pair is scored across temperature, pH, hardness, habitat baseline, behaviour conflict, and predation evidence instead of using one generic temperament label.
Does the matrix support shrimp and other invertebrates?
Yes. The planner supports fish, shrimp, and freshwater invertebrates with dedicated chemistry, behaviour, and predation risk handling.
What should I do with a low or risky score?
Open the pair detail and review factor cards. They show whether the issue comes from chemistry mismatch, territorial pressure, or predation so you can avoid or redesign the pairing.
Can I use the compatibility matrix on mobile while planning stock?
Yes. The same run is available in a touch-friendly pair board with filters and a compact detail view built for smaller screens.
