Best Live Food for Oscar Fish

Oscar fish, being omnivores, enjoy a variety of live foods. Some of the best live foods for Oscar fish include mealworms, crickets, earthworms, insect larvae, and small crustaceans. Some Oscar fish owners prefer to incorporate small feeder fish such as feeder goldfish in their diet as well.

As for the feeding frequency of live foods to Oscar fish, it is recommended to feed them approximately 3-4 times per week. Live food will often excite the Oscar fish, but it’s important to note that overfeeding should be avoided as it can lead to health problems. Always ensure that the live food is free of parasites and harmful bacteria to keep your Oscar fish healthy.

While live food can be nutritious, it should not be their only source of food. Supplementing their staple pellet feed with live foods would be ideal.

Homemade Oscar Fish Food

Homemade Oscar fish food is great because it contributes to a varied diet. While satisfying all nutritional needs with homemade food alone may be difficult, it would be a great supplement to their staple pellet food.

Here are some examples of homemade oscar fish food:

  • Shrimp:  Oscar fish do eat shrimp. They are one of their favorite foods. In order to prepare frozen shrimps for feeding, be sure to thaw the shrimp and cut it into appropriate sizes. Since Oscars do enjoy eating shrimps, be careful not to overfeed them.
  • Other Seafood: In addition to shrimp, other seafood such as scallop, clams, squid, and mussels are great for feeding Oscar fish. Since many of these seafood is available frozen, be sure to thaw it out and cut into appropriate sizes before feeding.
  • Fish: Oscar fish
  • Vegetables: Oscar fish eat various types of vegetables including spinach, peas, broccoli, corn, lettuce, cauliflower, cucumber, zucchini, and carrots. Vegetables that are hard should be boiled or blanched to make it softer and easier for the Oscar fish to consume.
  • Fruits: Oscar fish eat various types of fruits such as bananas, apples, mangos, melons, grapes, pineapples, water chestnuts, cantaloupe, oranges, and watermelons. These fruits are great nutritious treats.
  • Repashy: You can prepare your fish food from home with Repashy fish food as well. It is purchased as a powder, which is then mixed with water to make a gel based food. For Oscar fish Repashy Community Plus is recommended.

Oscar Fish Food Price

The cost of food for Oscar fish can vary depending on the type and brand of the food. However, it’s generally not too expensive. You can get some quality fish foods for approximately $20 per pound, which may last you up to a month.

Here’s how we calculated how long a pound of food will last for an Oscar fish:

If we consider an average adult Oscar fish weight of about 3 pounds (1361 grams), it would eat approximately 13.61 to 27.22 grams of food per day.

Now, if we convert 1 pound of fish food to grams, we get approximately 454 grams. So, if an Oscar fish eats around 13.61 to 27.22 grams per day, a pound of fish food would last approximately:

  • At 1% of body weight: 454 grams / 13.61 grams/day ≈ 33 days
  • At 2% of body weight: 454 grams / 27.22 grams/day ≈ 17 days

So, a pound of fish food would last for a 3-pound Oscar fish anywhere between 17 to 33 days, depending on the percentage of body weight it consumes daily. Please note that these are rough estimates and actual consumption may vary based on the specific diet and feeding habits of your Oscar fish.

If your Oscar fish is smaller than 3 pounds, the pound of fish food may last much longer than a month as well.

Vacation Food for Oscar Fish

Feeding an Oscar fish while you’re on vacation can be a bit tricky, because you want to make sure they are able to maintain their health while you are away. Here are some options:

  • No Feeding: If you’re only going on a short vacation, Oscar fish can survive without food for a while. A healthy Oscar fish does not demand food so frequently. The actual duration of their survival depends upon the age and size of the fish. A juvenile Oscar fish can stay without feeding for almost two weeks, whereas an adult one can go for around four weeks.
  • Ask a Neighbor or Friend: If you’re comfortable with this option, you can ask a neighbor or friend to feed your fish while you’re away.
  • Vacation Feeder Blocks: These vacation feeder blocks gradually dissolve in the water, releasing food particles for the fish to eat. They come in different sizes that can last from 2 days (weekend blocks) up to 14 days (vacation blocks). They are commonly used but they do come with some risks. Some fish may not eat it, and the uneaten food can impact the water quality. Other fish may end up eating all of it at once, which is not good for the water quality and fish’s health either. If you do decide to use vacation feeders, it should be tested beforehand so you know what to expect. This is one of our least favorite options.
  • Automatic Fish Feeders: Automatic fish feeders are often considered a better alternative to vacation feeder blocks. They allow for more control over the amount and frequency of food being dispensed, reducing the risk of overfeeding or underfeeding. However, it’s important to ensure that the feeder is working properly before leaving for your vacation.
