How Often Should I Feed My Fish In My Aquarium. Some Fish Are Messier Than Others. Larger more sedentary fish can go longer between meals than smaller more active fish.
When you feed the fish more the fish will start producing more waste. How often you need to feed your fish depends on the kind of fish you have. For the most part feeding your fish once or twice a day is sufficient.
This gives the fish what they need to remain healthy and at the same time doesnt create any maintenance problems in the future such as more water changes to reduce nitrate created from uneaten food left on the bottom of the aquarium.
How Many Fish. However some owners prefer to feed their fish twice a day. A good rule of thumb is to see how much your fish can eat in three minutes or how much they can eat before their stomach starts bulging. Usually I feed my fish flakes or a mix of flakes and shrimp in the morning and Ill feed them algae wafers at night.
