Can you provide additional information? Water parameters? Ammonia? Nitrite? Nitrate? What size of tank? How long has it been set up? What have you been trying to feed it?

This will help to get a better idea of what's happening. From the picture posted something is likely off with the water. The goldfish the aro is with are holding their dorsal fins clamped towards the body which is not a good sign.

Those goldfish are gonna make keeping his water ammonia free complicated. Dirty carp. I would say the above are right is likely a temp issue but those 3 in a 20 gallon that is likely not cycled will not end well.
Should read up on the nitrogen cycle if you have not already.

Please read below. I would give it back to the fish shop if you can't provide these conditions.

The silver arowana is best kept in large aquariums with tankmates that are just as large or too big to fit into its mouth. The silver arowana can share space with larger fish that inhabit the lower strata of the aquarium, such as clown knifefish, large plecostomus, oscars and other large cichlids. The silver arowana can also live alone or in groups of three. The Australian arowana is best kept alone in its own aquarium. Due to its physiology and natural habits, a long tank is desired over a tall one, with recommendations of the aquarium measurements equal to three times the length of the arowana. A minimum tank size of 72 by 30 by 24 inches is ideal. Two hundred gallons is the generally accepted minimum capacity. Ideal water conditions are pH of 6.0 to 7.5 and a water temperature range of 75-83 degrees Farenheit.

The silver arowana requires a long, rectangular aquarium with a lot of surface area to patrol as it spends most of its time swimming back and forth on the surface looking for food. A lid is also required as the arowana is a very accomplished jumper. Because it eats so much, the silver arowana produces a lot of waste material, so frequent water changes are a must. Bi-weekly water changes of 20 to 25 percent are ideal. Pay special attention to water conditions and test for ammonia, nitrate and nitrites regularly.
