Fish of all kinds (including goldfish) will pick on a weak fish if there is one in their vicinity. In general goldfish are peacefull. During spawning season (spring) though, the males will be seen nudging the females in order to get them spawning. So no, they do not normally 'pick on their tank mates'.
Fantail goldfish are a hardy breed, strong swimmers and they compete well for food with the ryukin, shubunkin, comet or common goldfish; making these goldfish breeds good tank mates for your fantail goldfish.
Yes, you can have one goldfish in a 20 gallon tank, but no other tank mates, not even a snail.You still need to make sure you have a filter, and that you do regular weekly water changes as goldfish produce a high amount of waste.
Usually a female goldfish mates with a male goldfish!
Goldfish can live for quite a long time with proper care including tank size, excellent filtration, regular weekly water changes, feeding a variety of food, and only putting them with compatible tank mates.
Yes, goldfish are known to eat smaller fish, especially if they are hungry or if the smaller fish fit into their mouths. It is important to keep goldfish in a suitable environment with appropriate tank mates to prevent any potential issues.
Yes, big goldfish may eat smaller goldfish, as they are known to be opportunistic feeders and may consume smaller fish if given the chance. It is important to provide adequate space and appropriate tank mates to prevent any potential aggression or predation.
No, but it also depends on the size of the goldfish. I would say to go pick out 2 goldfish, put them on hold and go back home and see if you think they will fit, if you are still not sure, try bringing the tank to the petstore and ask them what they think.
Yes
You can pick them up at about any pet store that sells goldfish. We have a white one we picked up at Wal-Mart and a black one from Petco.
It is important to remember to put things in a goldfish tank, even goldfish get bored. Some of my suggestions for tank decor are artificial plants and a "hidey hole" for your goldfish.

You should not have goldfish and platies in the same tank ever.
