dont listen to this guy. unless the arowana is only 2". no arowana deserves to even start life in a 75. unless its for a growout purpose only with the larger tank in another room filled with bigger fish that might eat him. but do not go buy a 75gal tank for an arowana to live
 
Assuming it is a small aro, start with the biggest tank you can get/afford. Don't stress, it will grow, you will love it ( because it is the best fisgh in the world ), you will watch it grow and both of you guys will, in time, grow into a bigger tank..just don't stress and don't refrain from enetring into the aro universe just because your tank is not exactly the right size.

I am assuming, and I emphasize this, that it is a small aro, ok?
 
I believe the minumum tank size for a Silver Arowana should be at least the following;

The tank length at least 3x the length of the aro and the depth(front to back) and the hieght should be at least equal to the length of the fish.

So for me a 180 gallon would be great for a silver that was up to 24" long. Probably could go up to 26".

I started out with a 3.5" silver he was in a 55 gallon until 8", he is now 13.5" and in a 75 gallon tank and will be moving to a 120 gallon in three weeks and then by the end of summer he will get a 8' x 30" x 30" which I hope he can live in for many years. Once he does out grow I am planning to build a 10' x 4' x 3' tank in my basement.

But it's ok for a RTC to start out in a 60 gal?:screwy:

You can keep a Silver in a 75 gallon untill it is 16" long.
 
This comming from a kid who built a tank just for his arowanas.

Keep in mind that the silver and black arowana ( not so much sure about the black ) can get up to 4ft in the wild. In most home aqariums they will only grow to around 2 ft and if given the proper care 3 ft. I would say anything around 3ft wide and 6-7ft long would be good.

also keep in mind an arowana will grow anywhere from 1-3" a month if they eat properly and once they hit 18" they slow down.

did u miss my other portion of a statement of "unless its for a growout purpose only where the larger tank has tankmates that could make a quick snack out of him" ? the main reason why i said no arowana should start in a tiny tank, is basically for those who always say "ill upgrade later" and usually never do. but if u already have the tank lined up for him, i see no reason why he can't start out in a 10gal tank... but remember. any fish in a small tank, will grow slower then if in a big tank. might as well start in the big tank.

cmon man. why derail this thread. i have a 60gal, 100gal, 150gal, 400gal. it doesn't matter what size tank any of my fish start in, either way there gonna live happy.

can you see me puttin ga 2" rtc in a 150gal tank with 2ft silvers n gars? be real
 
Boydo, your in the ball park. I know you have one of the most impressive tanks I've seen. I know its large, but how many fish do you have in there??? The question on this thread was the min. to house a single silver.

:) Lots of fish:) Your right it's a large tank, so are the fish, I'm planning to build a 2500 gallon tank for them in the near future:headbang2. They get so big so fast. Sure a 180 gallon would work, it would be best if it had at least a 72" x 30" foot print, anything smaller than this is too small for an adult Silver. Thanks for restating the question for me, your help is always appreciated:) .


The most important thing besides the size of the tank is filtration, and maintaining excellent water quality.
