Poor Water Quality
Most LikelyHigh levels of ammonia, nitrites, or nitrates can irritate the fish's skin and gills.
Aggression from Tank Mates
Most LikelyOrchid Dottybacks can be aggressive, especially towards similar-sized fish, leading to stress and erratic movement.
Inadequate Diet
PossibleInsufficient or poor-quality food can weaken the fish, making it more susceptible to skin irritations.
External Parasites
PossibleParasites like ich or flukes can cause skin irritation and lead to flashing behavior.
