what is the biggest known arowana to ever live in a tank.
or
how large do they get in the tank?
ive been told 3 feet, is that going easy about it. or do they actually get bigger in tanks
Answers:
Tank kept ones Chris are usually 3 feet sometimes a little bit more. But that does also depend on spacing. I am full well sure say you had a massive 1000 gallon tank, you kept the water quality perfect, you'd get it to grow out a full 48 inches. But in practicality for answers, how many typical home tank keepers would have a set up over a 150? If I were betting I'd say your typical max home tank is about 55-75 gallons simply because families with children have too much of thier floor space and budget already tied up. I'd go and research to see if there is record tank kept one if you want. I'll also give you a few other links that will support the length estimates of tank kept ones too.
Give you an idea on Arowana. There is a clip on You Watch TV, that shows an Asian Arowana pair that actually spawned in a tank. That is a very rare occurance to be honest. I am sure that tank must have been at least 500 gallons. I'll let you know what I find in a follow up.

Chris the simple facts here are this. Bigger fish as with most bigger tropicals don't reach thier full potential simply because the enviroment in a tank is not the same as a river or lake. Very rarely do you see tank kept fish, that are considered monster or tank busters reaching the same size as they do in the wild. If you ask around to other Arowana keepers, you're told get this or that on tank sizes. I've even seen someone say you need 700 gallons to keep them and thats just absurd. There is a clear difference between breeding and keeping and sometimes people just need to realize that you can't compare and apple and orange simply because they are a fruit. The facts of the matter is this, your tank at 250 gallons is not going to stunt your fish no matter what some online id posts on a link. I can tell you from having kept several that a 250 will be fine, and the day one of mine die from "stunting" or abusive care, I'll make sure to write you out an apology letter for misleading you lol. Your call who you want to listen to is the way I see it. If you want to follow other advice, that's by far your right and you certainly are not going to offend me because I am not on a quest to prove anything nor have a massive ego to stroke. If it ain't broke, don't fix it :) In the mean time, I'll go back to researching what you really asked for ok?

dude, your going to need a big tank around 300 gallons for a silver arowana. its simple really,if you cant get than many gallons, there are literally hundreds of other fishes you can get.
A smaller arowana species that you might be interseted is jardini arowanas. Alittle smaller but crazy aggressiveness. It is hard to find tankmates for jardinis are they will try and kill anything that enters the tank.
Public aquariums, often have huge 5000+ gallon tanks with full grow arowanas. Some about 40-60 inches i believe.
Yea you can keep a fish in a small tank, but does it make it right...no. As the fish will be stunted.
But anyway, silver arowanas might not be for you. Try really looking into jardini arowanas. One of my favorites, but like i said they will probably be the only thing that can live in that tank besides a plated catfish like a pleco. They are fairly common, and will get smaller than a silver arowana. They look more like asian arowanas than silvers, but jardinis have less and a different scale number and pattern respectivly.
Check out this link on fishprofiles which shows my topic regaurding silvers. http://fishprofiles.com/files/threads/35...
I help clean my friends tank and he has a 50"+ silver arowana with a ~24" cross breed between asian and jardini, and a ~38" clown knife in there.
He built the tank himself out of acrylic sheets and its roughly around 1500g
He keeps it in his basement though because it is extremely heavy.
It is the biggest arowana i have ever seen. The weird thing about it he has never fed them any live fish.
