goldfish care

Bit confused. I have two comets, each around 2" body length in a 200l tank. I bought some sinking pellets, and the man in the shop said to feed them 4-5 pellets per fish. However, that looks like a very small amount of food compared to the size of their bodies. The instructions on the pot say...

I have two common goldfish in a 5 gallon, and I plan to upgrade to a 300-gallon stock pond when I can afford it. However, my parents would also like to put the turtles in the pond as well. I don't want the turtles to potentially harm the goldfish. So, I can either try to find a way to divide the...

I've had my Scuba Doo, my black moor, for about 8 months. Super happy and healthy little guy. I've noticed a white spot/growth on what looks like the anus area. I've looked it up and read other people's posts, and some say something about spawning? He's the only one in the tank though, so that's...

Hi! i’m not quite sure if this is where i’d make this post, but i’m new so please bare with me. I have two comet goldfish named poppy & johns — i’ve had poppy the longest and my in laws purchased johns about a week ago, at the time i was unable to quarantine him. so decided it would probably be...

I am thinking about getting a Black Moor Goldfish. I was wondering what size of tank would be best and if a filter would be needed? At first I was thinking a 5 gallon tank with an air stone, but I’ve seen several people saying they must have a 20 gallon at least? Would a 10 gallon tank be big...
