no it means that there very poorly and need lots of attention or flushed down the toilet
I think it is bad for them
Goldfish do not have legs. Goldfish do have fins, although the number of fins will depend on the type of goldfish.
a goldfish uses his/her fins for direction when it swims.
fins fins
A goldfish has about 1,500 bones inside of it.
no they don't loose there fins if they do they die.
Well goldfish move their fins of course.
Maybe you are seeing natural red rays in the fishes fins? If not then there is something wrong with the water. Change some (50%) water daily and see if the red markings disappear. Dont change all of the water.
The fins develop on a goldfish fry after about a couple days after they are hatched. Until then, they are not free swimming and look like a tadpole.
The common goldfish because its fins are not too delicate
There are many fins on a goldfish that act in stabilization. The two major ones are the pelvic and pectorals. The anal fins also help in stabilization but they don't play as large of a role in it.
It is very badly damaged and will probably die. -----improved answer ---- that's actually incorrect, unless there are signs that there was a fin to begin with, in which case it is probably fin rot... but if you are talking about those goldfish that swim super awkward and have no fins on their back, then you are talking about a celestial goldfish. some bubble eyed goldfish also come with no fins.
Sounds like hemmorage, and yes. That would be bad.
