The Silver Arowana is one of the biggest icons of fish keeping. Growing to almost a metre in length, they are certainly a showpiece. Originating from South America, Arowanas prefer a set up that's long and wide, but not necessarily deep as they spend all of their time at the surface,. But more important than space is the need for powerful filtration. The filtration should be powerful enough to handle the enormous bioload from this fish, but the flow must not be too powerful as they prefer more sluggish waters in their natural habitat. Frequent partial water changes are highly recommended to keep on top of the water parameters as the water quality can deteriorate surprisingly quickly, leading to eye and gill problems.
Decor is not particularly important to the arowana as it spends nearly all of its time just below the surface, but other tank mates might appreciate the hiding spaces.
Tank Mates
If tank mates are chosen, size must be considered first. The arowana has a surprisingly large mouth and will attempt to eat almost anything that fits in there. They can however coexist well with large armoured catfish, large cichlids, stingrays and other fish like tinfoil barbs. However, it is highly recommended that the arowana is the last fish to be added to the aquarium as they can be highly territorial towards all tank mates that are newly introduced.
Feeding
This is a surface dwelling predator with a huge mouth and an appetite to match. Feed cichlid pellets and lots of meaty foods such as mussels, lancefish, krill and cockles. It is a voracious eater and must have the best filtration possible to handle such a meaty diet.
A tight fitting lid is absolutely essential when keeping arowanas as they are accomplished jumpers.
