What should you do if your fish is not eating?

Here are some steps you can take:

Rule out water quality issues: Fish won't eat in poor water conditions—test the water for parameters like ammonia, nitrite, nitrate, pH, GH, and KH to ensure they are suitable for your fish species.

Inspect for external signs of illness: Take a closer look at your fish's body, fins, and gills for any external signs of disease, parasites, or injuries that might cause refusal to eat. Isolate the affected fish immediately.

Make sure you're offering suitable food: Ensure the food you're offering is appropriate for your fish type and size. Try varying food types, adjusting their size, or using enticing frozen or live foods.

Check aquarium stress: Evaluate if anything in the aquarium has recently changed or contributed to increased stress that could affect the fish's appetite. Ensure proper hiding spots, avoid crowding, and keep water flow at a gentle, non-obstructing level.

Temperature adjustments: Sudden temperature shifts can temporarily discourage fish from eating—gradually adjust by 1-2 degrees Fahrenheit per day until it reaches 72-78 F.
