Common Causes of Missing Scales in Altolamprologus
Poor Water Quality
Most LikelyHigh levels of ammonia, nitrite, or nitrate can stress the fish and lead to scale loss.
Bacterial Infections
PossibleGram-negative bacteria can cause fin and scale rot, leading to missing scales.
Stress
Most LikelyStress due to aggression, tank overcrowding, or rapid temperature changes can cause scales to fall off.
Malnutrition
PossibleLack of proper nutrition can weaken the fish's immune system, making it susceptible to infections and scale loss.
Genetic Factors
Less CommonIn some cases, scale loss may be due to genetic predispositions, though this is rare.
