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'.
No, they can not. Fantails are goldfish and goldfish like temperature from 63-750 . And no goldfish can not be with any tropical fish. It can only be with other goldfish they are likely to nip a little to pick on who's weak but it is not a problem.
Goldfish can produce over 1000 fry when they spawn this is why it is very important for goldfish breeder's to perform culling (pick out the best specimens and dispose of the rest). Goldfish breeder's usually select around 50-60 fry that appear to have good potential.
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.
Betta fish are very aggressive. They pick at their scales and then they're gone!
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.
Some common breeds of goldfish are: the Black Moor goldfish, the Ryunkin goldfish, the comet goldfish, the common goldfish, the Calico Fantail goldfish, the telescope eye goldfish, the bubble eye goldfish, the pearl scale goldfish and the Oranda goldfish.
No you cannot put a frog with goldfish; goldfish belong with goldfish
Because they are looking for food and may pick up gravel as they slurp their way along the bottom of the tank.
probably not.Goldfish usally eat ...well fish food.Crabs are to hard for them to eat. Unless its dead then they might pick at it.
The plural of goldfish is goldfish. It is the same as the singular.
Goldfish do not have legs. Goldfish do have fins, although the number of fins will depend on the type of goldfish.
