How long will a 6inch+ arowana out grow a 125g

[pbass2005]

I'm getting a silver aro to day and was wondering how long will it take for him to out grow a 125g grow out tank

And once he out grows that tank I'm getting a 440g it's will be 96 by 48 by 24

I'd say within 4-8 months max.
They can grow 1-2¨/month.

I knew they grew fast but not that fast but he will be fine when he is in their for that period of time

Hello; Fine is a questionable term. So much will depend on how you as the fish keeper alter the tank care as the fish grows. Right now you may get by with a 50% water change (WC) once a week. In a couple of weeks it may be 50% twice a week . In a month it may be 75% twice a week and so on. As the fish grows it's metabolic activity increases. My guess is being a fast grower adds to the metabolic bio load.
I also think these fish are messy eaters so that will add to the water quality issues.

Thank you I love how different they are from other fish I gave him food last night it was so cool and thank you for telling me how much water change I have to do thanks

It seems the arowana really hit a growth spurt around the 12" mark, but they definitely grow fast and it varies fish to fish for sure. It will need an upgrade when it his the 16-18" mark or so gven a standard 125 is 21" front to back.

Hello; My suggestion is to try to keep the nitrates around 20ppm and us that as a guide for amount and frequency of WC.

Alright thanks for the help

Very true all what you said, though actually Arowanas aren't really messy eaters, in fact quite the opposite, they mostly swallow their food whole and and it's gone, they don't seem to like chewing on food. But yeah for sure metabolic load will increase exponentially with each inch grown, that 125 is definitely suitable only as short-term housing.
