Pellet fish food may be appropriate for your fish, depending on the natural diet of the fish and the contents of the pellet. There are many formulas of fish food available; this is true of all varieties of flake and pelleted fish food.
The formula of the fish food pellets or tablets is very important to consider for the feeding requirements of the fish in your tank. If you have a naturally carnivorous fish that will accept pellets like Apistogramma, then it is important to have a food that meets the nutritional requirements that the fish would get from a natural diet. Remember that tropical fish foods are designed to supplement a natural feeding and as a result they should mimic the nutrition elements that the natural diet would give to your fish.
There are several varieties of pellet fish food available on the market today. The type and size of pellet should be a consideration when looking at the food. There are meat based pellet fish foods that contain natural prey meats and vitamins that are essential to the fish's diet. There are also plant based fish food pellets that feature plant based nutrition. Ensuring that you are feeding the right type of nutrition to your fish is an essential part of a healthy aquarium.
Pellet/tablet size is also very important. If the pellet is too big the fish may have trouble ingesting it. When the pellet ends up destroyed in the tank it can cause a plethora of problems that are often associated with the overfeeding of fish. If the pellet is too small it could be uninteresting to the fish and end up dissolving at the bottom of the tank. Either scenario can cause problems not only with the nutrition of the fish but with the overall health of the tank.
If you have made the decision that a pellet fish food is right for your fish, ensuring that it provides the nutritional elements your fish needs, you are ready for the next step. What your fish may need varies depending on the size and species of the fish. Fish are like people in that they need a certain amount of fat, protein, carbohydrates, vitamins and minerals. Reading the label of the fish food that you have selected can be the best way to ensure that you are giving your fish proper nutrition. If the fish food is missing a certain type of mineral or is lacking in protein essential to your fish's diet, then it may be a good time to start looking for another food.
Pellet fish food like other forms of fish food has a shelf life. Looking for brands that carry an expiration date can be a good way to ensure that your fish food is providing the quality nutrition. Because of the cooking process most of the pellet fish foods begin to lose their nutritional value after one month. It is vital to your fish's health to make sure that pellets are either used or thrown out after that month marker. Buying bulk in fish food may save money, but unless you have the quantity of fish to consume that amount of food; the pellet fish food is better bought in portions that can be used within one month.
Finally consider the fish's taste. You may find a fish food that meets all the nutritional landmarks, is the right size and made of the right materials; but your fish won't eat it. Giving an adjustment period is important but if your new pellet fish food sinks to the bottom and dissolves there, it may be best to switch to a different type.
