Common Causes of Sinking to Bottom in Eartheater Cichlid

Internal Parasites

Most Likely

Parasites like tapeworms can cause bloating and weight loss, leading to the fish sinking to the bottom.

Bacterial Infections

Most Likely

Infections like dropsy or columnaris can cause fluid accumulation and swelling, making the fish unable to swim properly.

Poor Diet

Possible

Lack of proper nutrition can lead to muscle weakness, making the fish more prone to sinking to the bottom.

Stress

Possible

Stress from tank mates or poor water quality can cause the fish to become listless and sink to the bottom.

Old Age

Less Common

Senior Eartheater Cichlids may naturally experience muscle weakness and sinking due to age-related issues.
