  • Stress and Agitation: Poor dietary habits, including excessive fish waste consumption, can lead to stress in clown loaches. This can negatively impact their behavior, coloration, and overall well-being.
  • Deteriorating Water Quality: Elevated levels of fish waste in the tank can lead to a rapid decline in water quality. This can cause stress to the fish and create an environment conducive to the growth of harmful pathogens and parasites.
  • Increased Risk of Parasitic Infections: In tanks with high levels of fish waste, there is an increased risk of parasitic infections. Pathogens thrive in such conditions, posing a threat to the health of the fish.
