Can koi fish eat dry oatmeal?

Yes, koi fish can eat dry oatmeal, but it should only be given as an occasional treat rather than a staple in their diet. Oatmeal can provide some nutritional benefits, but it lacks the essential nutrients found in a balanced koi fish diet, such as high-quality pellets or fish food. Always ensure that any treats, including oatmeal, are finely crushed to prevent choking and facilitate digestion.
