Oddballs are unusual freshwater aquarium fish that do not fit neatly into the common community categories. This browse group can include specialist predators, unusual bottom-dwellers, and niche species with highly specific care requirements.
Behaviour in this category varies dramatically by species, from shy nocturnal fish to territorial predators and specialist grazers. It is useful as a discovery bucket for the app, but it should never be treated as a shared care type.
Use this group mainly for browsing and discovery, then rely on the individual species profile for real care guidance. Many oddballs need specialist diets, secure covers, careful tankmate selection, or unusually large and well-designed aquariums.
