I thought I was pretty close to being able to set up my 180 gallon tank and get a Jardini Arowana, but I noticed that the top frame is cracked, and until I can find a solution for that, the project is on hold. I had the idea of getting a 150 gallon Rubbermaid stock tank and setting it up indoors for a Jardini, but I have a few questions. Has anyone done this with an Arowana? Is 150 gallons big enough, at least until I can eventually get the 180 set up? And also, what material should I use for a canopy to keep the fish from jumping out?
