If your goldfish is not being attacked by a tank mate (which would mean that you either need to remove the aggressor, or place the beaten up fish in another tank) then it's likely a water quality issue.
Typically when something like ammonia is at toxic levels, this will begin to shred & rot your fish's fins.
If this is the case, you need to do an immediate 75% water change in your tank making sure that the new water is the same temperature as the old water, and that you use the recommended dosage of aquarium water conditioner per the instructions on the bottle.
You should make sure that you are doing regular maintenance in your tank which includes at least a 50% water change every week; more if your tank is too small or overstocked.

deep roots?

Since a rosebush is not an animal, the thorns must help the plant by protecting it from being eaten.
actually both they help control the race of smaller animals. To do that they kill them and hat is a scary thing to be eaten alive.
get a goldfish and test it out i have a gold fish it dosent really make a difference
It keeps harmful materials (ex. plastics) from getting into the ocean, and being eaten by the animals.
A goldfishes colour does not help it survive. The goldfish is a man developed (through selective breeding) species and did not evolve naturally. When they are released in the wild, they breed and the brighter coloured ones get eaten more readily because they are relatively easy to see. This eventually (over the years) makes the species slowly return to their original colouring which is a drab green/brown on the back with a silvery belly.
A male goldfish developes white spots when he is about to fertilize the females eggs. It could be possible that you have a male and a female! Congrats!!!
Goldfish are omnivores and cannibals so other larger goldfish can be predators to your smaller goldfish. Other predators are carp and koi. None swimming predators can include raccoons or house cats. Only place goldfish into an aquarium with other similar sized goldfish. By having a deep enough and wide enough outdoor goldfish pond with a few aquatic plants living in it for your goldfish to hide in, will help them avoid becoming prey to those predators.
They hide in tall grass with there stripes that help them with that. When zebras are cornered they us there hind legs and kick them with great force.
