How many silver arowanas for a 650 gallon tank?

[EmrePekdeniz]

Huge is a relative term.

Yes, 650 gallons is a lot larger than 450 gallons for example.

Whats your point? Is the sheer volume supposed to make up for the inadequate width?

Yes, unless or until the fish are 70+ cm long. Which would take years. This means the fish have a lot more space to swim on a straight line.

Anyway, I'll just relay the info.

Wow a real mathematical genius. You need put that genius to work and provide for your aro, other then a small triangle.

As you've so wonderfully said, "huge" is relative. A juvenile arowana is a lot smaller than an adult arowana, for example. I hope your biology teacher has taught you that much. Then again, I guess you never had grow-out tanks either. I see.

Grow out tanks are fine. Just a little logic need be applied as to the shape of the tank. As well as knowing when the tank will be or has been outgrown.

Okay, rectangles are good and triangles are evil. Because everybody knows that arowanas inhabit perfectly rectangular water bodies in nature. And a 130 gallons tank is too small for a 9'' arowana which I'll be keeping till summer. Whatever.

man, this is turning into a real pissing contest.

You askeda very generic question. You never asked about juvies. If hes getting a 650why would we assume juvies? Too many people come on here and ask this question and don't like the answers they get or only want to hear answers they want to hear. So one can understand the frustration.

I see so now your tank has grown by 30g. Is that the volume of the entire tank or the water in the tank? I only ask since your tank is only 1/3rd full if I remember correctly?

I don't know about how many rectangular or triangular bodies of water are in the amazon region. However I have observed that arowna will not swim into and area that they cannot swim out with a forward motion, obviously since they are very bad at swimming backwards. The triangular shape of your tank creates such areas, this contributes to the reason your aro behaves the way it does.

I hope not. As I've said, I'll just relay the info to the original tank owner. Thanks for all replies. I was trying to dissuade the tank owner from getting giant Pangasius catfish, which aren't suitable for any kind of aquarium in my opinion.

You do amuse me. The tank is 500 liters with 100 gallons of water, i.e. ~3/4 full. It has never been 1/3 full, except when there were no fish in it. Sorry, your memory fails you.

And a triangular tank doesn't create dead ends for an arowana, unless you have a very odd tank with obtuse angles.
