I have an idea for a 55 gallon setup. It would include a small number of goldfish (3-5 depending on recommendations here), 2-3 weather loaches and small shcool of white clouds, maybe 5-10. What would be the best combo here? I figure I have the white clouds to shcool around and they'd look very nice, the goldies to add some color and the loaches will clean the bottom of any food that falls through. I am going to get 2 Penguin filters for it and decorate with plants native to China, if I can find any that is, some drift wood and build some caves for the loaches. I have a nice cool spot all picked out for it too. So does this sound good? Please tell me the maximum amount of each type of fish I can put in here.
