E' un pesce che raggiunge dimensioni imponenti, dai 60 cm a 1 metro e i 6 kg di peso, in alcuni stati, per determinate razze. Da adulti sono grigio-argentati, mentre invece per quanto riguarda l' arowana asiatica esistono varie colorazioni.

Vive a lungo, fino a 20 anni. Sono molto aggressivi e territoriali, gli unici pesci compatibili, sono grandi pulitori catfish, ciclidi come oscar oppure le razze d acqua dolce, ovviamente in acquari molto grandi. La vasca dovrà essere sviluppata sulla lunghezza e dai 700 ai 1000 litri a causa delle sue dimensioni, attenzione sono saltatori per natura, quindi utilizza vasche coperte e prive di eccessivi arredi, non è ovviamente un pesce adatto per gli amanti dell' aquascaping e dei dettagli estetici in acquario. Necessita di un ottimo sistema di filtrazione e frequenti cambi d' acqua, la corrente in vasca non deve essere forte e illuminazione non eccessiva. Sono carnivori, mangiano cibo vivo come piccoli pesci, insetti e uccelli, noi andremo a fornirgli da avannotti cibo secco e larve di zanzara, poi piccoli pezzi di pesce congelato, totani, gamberetti, grilli, camole e rane.
