Common Causes of Fin Rot in Eartheater Cichlid

Poor Water Quality

Most Likely

Overcrowding

Most Likely

Dietary Issues

Possible

Poor Diet

Possible

Feeding low-quality food or too frequently can lead to digestive issues and poor overall health, which can exacerbate fin rot.

Physical Trauma

Less Common
