Feeding tropical fish
If, like many amateur tropical fish owners, you feed your fish once a day with store bought tropical fish flakes, you need to be very careful to not overfeed them.
We all panic about underfeeding our pets, as we do not want them to become undernourished and, therefore, ill or even die. However, you are more likely to damage your fish’s health by overfeeding them.
If there is too much food, it will break down in the water and become harmful to the fish. It will clog up the pump and filter, and will lead to more dark green scum all over the tank. You can always give them a second small feeding if necessary, but it is very tricky to remove excess fish.
A general rule is to only feed as much as will be completely consumed in three minutes. Stick with that and your fish should be healthy and happy.
