Substrate etiquette
Corydoras whiskers are abrasion sensors, not armour. Sharp crushed coral or chipped gravel causes chronic barbel wear that invites infection even when ammonia reads zero. Rounded sand with gentle maintenance keeps their barbel tips intact and encourages natural sift feeding behaviour.
Group dynamics
Keep at least six conspecifics so tight shoaling reduces skittish glass-surfing. Sudden hiding after years of confidence can mean nitrite spikes, harassing tank mates, or heater failure - verify temperature before assuming “personality.”
