new coldwater aquarium
Just brought my goldfish in from the pond for the winter. Are there any kind of algae eaters, bottom feeders that I can get for a coldwater tank? Water temp around 72F and no heater. I have a 13 small goldfish and about 5 plants.
If I just do 5-10% water change each week (I was told that was recommended) do I need to get an algae eater?
