Owners should first rule out environmental factors before considering health issues.

Common Causes of Rubbing Against Objects in Horseface Loach

Most Likely

Ammonia, nitrite, or nitrate levels above safe limits can cause stress and lead to scratching.

Poor Water Parameters

Possible

Dietary Issues

Possible

An unbalanced diet or lack of certain nutrients can cause discomfort and lead to rubbing.
