I'm thinking of getting a Black Arowana

  • We are currently upgrading MFK. thanks! -neo
It will be fine for a long time in that tank. For an adult, however, the tank should be 6+ feet long and at least 2.5-3 feet wide.
 
I've seen Aro's in stores in the tank dimension you mentioned.... they look cramped, and are usually just for display until someone purchases them.
 
yup!:popcorn:
