Like goldfish
Try Shubunkins. If this is what you want. they look like goldfish but they are coloured with black blue white and gold. and they arent hard to get. They are as common as gold fish
If they're both male or female they are fighting. If one is male and one female then they are preparing to mate
because it is a goldfish stupid
They look like they are tired but they aren't :)
They are a fancy goldfish (Carassius auratus). They were bred to have scales that look like pearls.
a female goldfish
YES
Shubunkin is just a fancy name given to a specifically coloured Goldfish. Breeding one with a Golden coloured goldfish will result in about 33% that look like a Shubunkin and 33% that look like a Golden coloured goldfish and 33% that look like a mixture of the two. The above results would only be accurate if the breeder fish are properly line bred and their lineage is guaranteed. Otherwise you could get anything from coloured goldfish to uncoloured goldfish and a mixture of any kind of goldfish including Comets, Fantails and Veiltails.
