My arowana is finially gona come by mail

  • We are currently upgrading MFK. thanks! -neo
Of course he has ..haha When small/medium, all other predators could eat it, like Wolf, TSN, Dorado, Payara, Jau (Paulicea lutkeni), Filhote/Piraíba (Brachyplatystoma filamentosum). Other examples, like Ariranha (Brachyplatystoma filamentosum), and even a Onça Pintada (Panthera onca) could capture one of this fishes IF they swim in shallow waters (what probably not happens). When BIG, guess there are no more predators for him ! ;D

RTC has no predators in his habitat?

Sounds like to avoid making a costly mistake, further research is needed. There is a good chance you RTC will eat the arowana, or at least kill the arowana while trying. Both the fish you are interested grow extremely quick, you need to be sure on your ability to provide proper(multi-hundreds of gallons) housing within a year.
