I have a semi bare bottom tank and the goldfish like it. I have pots for my plants that way i can easily move them around. In my opinion fish like us have a sense of curiosity, so they enjoy having somthing in the tank.
two my goldfish started look like they got ich, i have been treating for a week or so. And now only one is sick, but i was looking online for some symptoms an velvet disease came to my eyes. the fish is acting strange i will say, sometimes acts normal and then Goldfish star swimming like crazy bumping in to the walls of the tank. If any body see this, and can help me
