your cat If in an outside pond, it isn't unusual for a Heron to take them.
yes, they are scavengers and will eat almost anything.
best to do flake or pellets food feed 3 times a day do how many about 2 or 3 per goldfish not too much. Do tropical or goldfish food to feed goldfish.

pond
A goldfish can live in an opaque glass tank as long as you keep up with necessary water changes. Like a small outside garden pond goldfish are only viewed from the top.
yes
The goldfish will eat the mosquito's larvae before they can leave the pond and fly.
Usually when an animal kills another animal it eats the body but it is possible that an animal could kill another animal and the dead animal's body could fall into a small stream or pond where it could decompose and pollute the water.
I have never heard of a "Pond Rocket Goldfish" and I can find no listing for such an animal in any fish reference book. That fact suggests to me that someone has made up name for a fish they didn't know how to identify. If the fish is a basic goldfish shape and has a tail that is very long (about half to one body length) it is probably a "Comet"
This is a literature question not a goldfish one.
no the goldfish would it the tadpole
