arowana tank size

[kody1192]

is a 150 gallon tank big enough for a full grown arowana it says they can get almost 4 feet at full length but about 2 foot is common anyone want to help me out here

I doubt it. I would think that 200gallons would be minimum tank size. I have seen arowanas in fish stores in 200+ gallons and the tank still looks small for them...

dimensions are more important than gallons size. for australians (jardini or leitchardi) or asians you can get away with a 180g 6x2x2, but long run it wil be cramped.

3' is common for silvers and blacks, so MINIMUM 30" wide and 8' long.
