Type of Fish Food

Two or three small feedings a day is better than one feeding per day. Only put in as much food that the fish will consume within 2 minutes. Overfeeding your fish will lead to poor water quality and stressed fish.



Brine Shrimp
Brine shrimp is a great food for getting your fish ready for fish breeding. It can also be used as an excellent treat for your fish. Use it as a supplement to the daily diet of flake fish food.
You can also create your own brine shrimp rather easily.

Blood Worms
If you have carnivorous fish you may want to supplement their diet with some blood worms. Your other fish will love these as well. Blood worms are high in protein and only feed them to your fish occasionally.

Live Fish Food
The food is still alive when you introduce it to the tank. Brine shrimp, Daphnia, Feeder Goldfish and worms are usually the main live foods given to tropical fish.If you plan on using live foods, caution is advised because feeder fish can bring fish disease along with them.

Earth worms can be a great supplement for your fish but don't feed them to your fish too frequently. Finding earth worms can be fairly easy but make sure you don't collect them from soil that may have contaminants such as lawn fertilizer.

Frozen Fish Food
Frozen fish foods are great for getting high quality, fresh food to your fish. These foods are usually high in proteins and fats so check the label to see exactly what you're giving your fish. Manufacturers are making frozen varieties of the many tropical fish food types, including brine shrimp, beef heart, bloodworms, daphnia, krill, plankton, silversides, etc. You can sometimes get the frozen fish food in cube packs that really makes it easy to dispense.
Using frozen fish food can be messy, to cut down on the amount of pollution added to your tank you may want to thaw the frozen food in a bowl and then slowly spoon feed it to your tank. Only put in as much food as your fish will eat as soon as it touches the water.
Feeding your fish high quality, frozen foods will really do wonders for them. You may start to notice that your fish have improved colors and they may even start breeding.
