I'm wondering, how big of a peacock bass or arowana I could fit in a 125 gallon fish tank?

And how many?

in a 150 gallon fish tank?

This is supposing that I have excellent filtration, and do my weekly 30% water changes.

I am wondering whether I should get a 125 gallon which I will find a lot easier or wait for that good deal on a 150 gallon. I figured that the best way to figure this out is find the difference between the sizes and number of fish I will be able to put in the different tanks.
 
125 or 150 is too small for P-Bass and Arowana. You should look at 240, minimum 210.
 
I am not planning to keep these guys for life. I was thinking how large they could get before I have to get rid of them sorta thing.
 
on the topic of P. bass how big do they get? a 125 has 18" of depth so a 20" fish could turn if you were to inclined to do so.

Now don't flame me for the comment but it is possible none the less.
 
Why do you want a fish "not for life"? I'm not trying to be mean, but really am curious. From my own experience, really it is much harder to get rid of a large fish....I got a Pacu (which was suppose to be for someone else once he grew)..they changed their mind, now I'm in quite the jam here, he is growing at a incredible rate, and can't find a home for him...so IMO, do not get a fish unless you KNOW you can keep it, it's a very hard lesson to learn...especially when you grow very fond of the fish and want the best for it, and there is nothing you can do about it and all you can do is blame yourself...believe me it sucks!

good call but most good lfs will take them off your hands and give you store credit. and if you just enjoy growing something out and getting a ny juvi when they outgrow there tank thats understandable as long as your not trying to make cash out of the deal. its like buying a fish once and insted of it dying on ya you can get a juvi trade in and only have to buy one fish insted of lots over time.


That is considering you have a LFS that will deal with you. they should b/c in the long run if they can get rid of it they will more then likly get a pretty penny out of it.
 
this is really common sense people, if your tank is about 18" wide, then your fish should not be any bigger than 16" at the most.

I never understood why people would ask these questions over and over and over. Follow this guideline and you can be more or less certain that your fish will be ok:

- measure your fish
- the length of your tank should be (at any given time) at least 4 times the length of your fish
- the width of your tank should be (at any given time) at least as wide as the length of your fish
- the height of your tank should be (at any given time) at least as tall as the length of your fish

so there you have it people! you got a 30" fish? get him a 120"x30"x30" tank.

unless we're talking about an unusually active fish (i.e. pacu) or an oddly shaped fish (i.e. stingray), the above guideline will cover all your "what size tank" questions.

Doesn't the above highlighted contradict each other. you say a 16" fish tops in a 18" wide tank then go onto saying that your tank should be at least as wide as the length of your fish. which would mean that a 18" fish could go in a 18" wide tank.
