Why does my Zebra Loach hide when I feed it?

Feeding in a public spot can make the Zebra Loach feel threatened. Try feeding in a secluded area.

How do I know if my Zebra Loach is stressed?

Signs of stress include hiding, loss of appetite, and abnormal swimming patterns. Ensure a comfortable and peaceful environment.

Should I change the tank substrate for my Zebra Loach?

Zebra Loaches prefer fine-grained substrates like sand or gravel. Avoid sharp substrates that can damage their barbels.

How can I prevent bullying among tankmates?

Choose compatible tankmates and avoid overcrowding. Keep an eye on the tank's dynamics to prevent bullying.

Is a lack of plants bad for my Zebra Loach?

While plants can be beneficial, a lack of plants may not necessarily cause hiding. Ensure there are enough hiding spots for the fish to feel secure.

Zebra Loach Hiding Constantly? Causes & Fast Fixes
