Hello all, I now have a 125 gallon standard 72" 18" 24" tank that houses four 5" goldfish and two 3-4" oscars, I have been worried about the temperature tolerances and how much waste they produce even at this size, I know I need to separate them, so I just locked up another tank i will be picking up tomorrow, It is a 36" wide, 36" tall and 28" deep, gallons? my question is should I move the goldfish into the new tank or the oscars? Also this tank will be against a wall beside the 125g, I plan on painting the back of the tank and was curious about color opinions?, I will be using play sand as substrate, with some lava rock and coral chunks.
Thanks for your opinions
