how long can i keep a silver arowana in a 180 gallon?

[anzo1993]

hello, i recently received a 2.5inch silver arowana from a friend who just got out of the hobby, only tank i had available was a 180gallon 6x2x2 with an endlicheri bichir of about 3 inches and an fx6 filter on the tank, wondering how long i could keep the little guy in there before he gets too massive? i wont be able to upgrade to a larger tank for at least another 2 years( current living situation being the problem)

1-2in per month till about 2 ft. It’ll vary but by two years it’ll be time to upgrade ASAP. Think you’ll just get by but will need to plan ahead.

okay so ill be cutting it very close then lol i plan on getting a 300 gallon at that time, should that be enough to keep him with a few bichirs?

Arowana are fragile until around 8-9 inches. The Silver Arowana should be fine with Bichir's.

Well think a 300g be fine for a while but it gotta be bigger. It’s been recommended atleast 8x4 so it’ll be bigger than a 300g.

A 400g woud be the minimum long term. Unless you get a specialty tank thats low, wide, and long like a 96x48x15 or something

Okay I'll take all this into consideration, I have alot of time to decide on dimensions, but I agree the tank needs to be at least 8ft ×4 ft
