How low can arowana handle?
 

Our temperature here right now is 23 deg celcius. And the water is also quite cold, how low temperature cam arowanas handle? My main concern is my pond as i'm unable to heat it due to size/volume. Any suggestions?

How deep is your pond ?

Pond water is 4 feet.

Shld Be no issue as the water near the depth will be warmer than the surface.

Bro Squid, you are residing in the Philippines right?:D

Thanks :) yup I'm in philippines . But not much sunlight past few months :) last summer was really really hot now i think colder than normal too:)

Water temperature is always different from atmospheric temperature, respond slower. We have a tank of arowanas in shopping mall at constant low temperature probably around 22 and survive.
I think the real danger is the sudden change of temperature.

thanks :) Temperature change should be gradual in my pond :) will just observe.

Bro, are the aros in question active and feeding?

Arowana is cold blooded, should be able to handle if its not too low (sub 10C).
reduce feeding when temperature is low. Metabolism rate is lower.
Take note of ammonium, nitrite and nitrate too. Bacteria react slower in low temperature too.
