Black-chin is a relatively un-researched condition that African Rift Cichlids can be affected by.

It is thought to be related to high nitrate levels and is rarely seen when nitrate levels are less than 25ppm.

Symptoms

Small grey/black irregular spots that initially appear on the chin but can spread along the underside of the fish so that it takes on a mottled appearance.

Cause

Not as yet identified, but thought to be caused by higher nitrate levels in the aquarium. Fish (such as African Rift cichlids) are though to be particularly susceptible as they come from water where nitrate levels are virtually zero.

Treatment

None - but reduction of the nitrate levels to below 25ppm should see a reduction and eventual disappearance of the spots.
