Those sound like the same thing, but its a terribly framed question.
yes in fact i have a normal orange goldfish and a panda at home in my fish bowl
the regular kind of goldfish is very hardy, so I believe it is very very normal. :)
The easiest way to find out is to go to the pet shop and she what type of fish they sell. I'd say the most obvious is the way they look, swim & behave.
It depends on the type. Normal goldfish cost $2.49 to $3.50; on the other end of the spectrum, fancy goldfish cost $27.99.
All goldfish types are the same species, so all types can breed.
It is normal most every goldfish does it, don't worry.
yes, yes they do. i have had a single common goldfish living in my fish tank for about a year now and have introduced 3 black moor goldfish into the tank , its been about 2 weeks now and their getting along absolutely fine. they are just the same as normal goldfish, just look different and different colour, but theyre behaviour is more or less the same. so nothing to worry about, enjoy your little guys :-)
If you buy a feeder goldfish, usually their lifespan isn't that long, because they are eaten by another pet animal soon anyway. However, I doubt that their lifespan will not be so different from a normal goldfishs' if you take care of them properly-just like a normal goldfish. It is just that they are normally sold in such crowded spaces that I think they are more prone to disease.

No, goldfish are best with goldfish. In addition, tilapia have different needs and are quite likely to be aggressive towards the goldfish.
I don't know if it is normal or not, but my sister had goldfish that would jump out of their tank when she would walk into the room. She would have to scoop them up and put them back in.
goldfish are not always one color because they have different species. Also, goldfish can change colors over time. They won't always be gold or maybe they won't always be white or whatever color your goldfish is.
