When fish go torpid, they stop feeding and slow body processes (almost like a kind of hibernation). They don't move much (or at all) and basically rest until the water warms up. This only happens when water temperatures reach near the freezing point. Most temperatures just above freezing, they will continue to feed on a limited and much less frequent basis, but still limit their movements.
Tumours would look like a growth sticking out of the body that is abnormal. Unless you have a fish that grows wen, such as an oranda (wen is that strange brain looking stuff that grows on their heads) then it's possible your fish has a tumour; unfortunately, there is no absolute cure as even if taken to a vet that specializes in fish and the tumour is removed, it typically grows back again.
Like goldfish
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.
junk
Like a gilbert that's what i named mine!
sort of. really really small ones. they kinda feel/look like goosbumps
No. They stay gray their entire life.
Goldfish do not get pregnant. They are egg layers. A female goldfish looks a bit chubbier than normal around the tummy when she is in breeding condition.
