Temperature Problem and others

[syntaxx]

Hi,

I have a silver arowana at 7-8" and my water temperature now is at 29C. I did 30% water change and still the same meaning my tap water is at 29C. How can i make it to 25-28C?

Thanks

thanks but i cant understand the link you have posted.

Also i am seeing a little lump on the back of it. Is it because of the water temp?

must be nice to have that kind of weather in middle of january. i assume you dont have a heater in your tank. could it be you have too much light (artifical or natural), too big of a pump inside your tank maybe?

Yes i don't have a heater in my tank i am just using a power head. Also could you possibly know what are the illness/diseases my fish will get for higher than the recommended temp?

i think 1 degree warmer is no big deal. it will just eat and poop more. as for the lump it will be helpful is you got a pic. i'm sure someone here can help.
