Answers:

Depending on the species, arowanas grow to three to four feet long. As it grows, you will need a huge custom tank of hundreds of gallons for it. I hope you, your wallet, and the weight supporting struts under the floor of your house are prepared for that!

They can get aggressive as they grow and crowded conditions will increase aggression. How big is the tank now?

Arowanas can eat live feeder fish but I don't recommend this as feeder fish can have diseases that your main tank fish can get. Try to get your arowana to feed on floating fish pellets or sticks. They can also be fed earthworms, crickets, thawed frozen silversides - anything meaty. They are carnivores and eat at the surface. They are good jumpers so make sure you have a secure cover on the tank. As the arowana gets bigger the cover will have to be clamped or weighted down since they are so large and powerful.

In the future please try to research fish adult sizes and requirements BEFORE you buy the fish. There are plenty of books and good Internet sites with this info.

Baby arowanas are often sold in pet stores to people totally unprepared for a four foot carnivorous fish. Most people do not have the capability to provide for adult arowanas. As it grows and/or becomes too aggressive for your other fish you will need to find a new home for it. Try the local zoo or public aquarium and if they do not have space for it try to find an aquarist through a local aquarium club with a huge tank that can properly acommodate it. Some pet stores will allow you to trade in fish that have outgrown your tank, too.

They can get about this big [holds up hands, far apart]. I'd continue to feed them on mice and small children until their at least 12 months old.
