It would be best if you reflected on Arowana’s diet as widely as possible to ensure they prosper and are maximally comfortable in your water. This implies that there should be more living food as possible to be included in the diet.

However, variety is important to keep your fish from developing a nutritional deficit. Crickets, cockroaches, and centipedes may be included as insect foods for the Arowanas.

Crickets are nourishing and have a minimal danger of transferring illness to your fish since most crickets are ill-free and so they rarely get ill.

However, it would help if you mainly chose farm-bred cricket since wild-caught crickets frequently become polluted with pesticides. Note that the wild crickets are not as bad as they could seem, only that they have come across many pesticides, making them a little bit contaminated.

Crickets are excellent vitamin A sources. Set yourself on live farms to reduce the probability of inserting chemicals into your aquarium. Frozen centipedes are also highly recommendable as they will improve your Arowana fish’s color and act as food for the fish at the same time.

 Always ensure that before cutting the small fish or amphibians to bite sizes and washing, the fat is completely cut, and no traces of fat can be traced. An aquarium diet of Arowana fish is inadequate without pellet food.

 Pellet foods should not be considered as the day-to-day meal of the Arowana. This may lead to starving the Arowana, and it can get stressed up and start jumping out of the tank.

Naturally, their hunger will also slow down. As such, you may feed your Arowana fish once daily for adults and sub-adults.

Fortunately, Arowana fish will lose food once they are full, so you won’t have to worry about overfeeding. To this purpose, if they take food, you may continue to feed them as this shows they are not yet full.

Just ensure that all the remaining food is removed soon after your meal such that the levels of ammonia are not increased, or any other toxic substance will not build up in the Arowana’s tank.

Live fish, such as catfish, goldfish feeder, and meadow fish, may perfectly replace Arowana fish’s wild diet.

You may feed these tiny fish with medicine and nutrition before being fed into the Arowanas and transferred to them. This prevents the small fish from transferring illnesses or diseases to the Arowana fish.

Goldfish may also be used sparingly in the diet of your Arowana fish. This is high in fat, important to prevent eye problems in the Arowana fish. However, too much of it may induce Arowana’s nutritional deficits. Isolate the Arowana fish for at least five days before feeding tiny fish to a fish in Arowana to prevent illness transmission.
