I am not a goldfish person so I will leave the care information to someone who has more knowledge and experience than I do, but here is a post on their adult size expectancy, http://www.aquaticcommunity.com/aqua...ad.php?t=47133When I go fishing I just throw sharp rocks in the water and wait for the dead fish to float to the top...

Everything happens for a reason. Sometimes that reason is you are stupid and make bad decisions.
I think my fish is adjusting well to the four gallon, He's laying on his side attempting to go to sleep on the bottom of the gravel.
A moderator on a fish forum should be able to identify an oscar... Don't you think?

Other than shape and size, a general rule is the more deformed, the harder to take care of.

The varieties can be split into 2 groups, hardy goldfish (comets, shubunkins etc) and fancy goldfish (fantail, oranda, celestials etc).
As a general rule, the fancy varieties are slightly more susceptible to illness and disease due to being selectively bred so much. Despite this, they are slightly more suited to life indoors as they can tolerate warmer temperatures than the hardy varieties (15-24C) and as adults they are a bit smaller than the hardy types. They are also not as active in my experience, so don't need quite as much swimming space.
However it's worth noticing that any goldfish can exceed 25cm in length and due to the design of their digestive system they are really messy in terms of ammonia production, so they're not easy to keep in tanks long term (you'd need a huge tank with an excellent filter, it is do-able, but there are easier fish to keep imo).
Some of the fancy varieties that grow a wen (the wart-like growth on the head) such as orandas require more protein in their diets to support healthy development. Other than that they all need similar food that is high in vege matter.
The hardy types are more resistant to disease and illness therefore easy to keep while young, but can grow to 40cm in a few years so really do fare best in a pond long term. Their colours are also more intense if you let them overwinter in a pond.
Hope this helps :)
