Overlay ecological pressures for a hypothetical freshwater community — thermal window, chemistry, space, predation, social tension, and dwarf shrimp safety. For planning and learning, not for declaring fish "compatible."
Simplified ranges and rules only. Does not predict individual behaviour, aggression, or disease. Your real tank and your observations come first.
Map overlapping pressures for a hypothetical freshwater mix — thermal window, chemistry, space/load, predation, social tension, and dwarf shrimp safety. For planning and learning, not for declaring fish “compatible.”
Simplified ranges and rules only. Does not predict individual behaviour, aggression, or disease. Your real tank and your observations come first — use the Keeper’s Log for what actually happens at home.
Species parameters (temperature, pH, body size, and behavioural tags) come from the Aquatic Rhythm species pack — hobby-consensus ranges cross-referenced against FishBase and SeriouslyFish. Each species entry carries a citation note.
The pressure engine checks thermal overlap, pH range intersection, bioload coefficient, predation mouth-size matching, fin-nipping pairing, and dwarf shrimp safety. It does not model individual personality, aggression history, or disease. "Elevated" and "High" labels mean the parameter warrants attention — they are not predictions of failure.
Verify species parameters against current sources before stocking. Your real tank and your observations always come first.

Aligned with living systems. All tools grow from ARA — they simulate and plan, but they do not replace observation.
