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.
Up to 6 species · 24 individuals total. Search by name or id (e.g. neon_tetra).
Aligned with living systems. All tools grow from ARA — they simulate and plan, but they do not replace observation.
