There could be three explanations that come to mind immediately. Goldfish tend to orientate themselves according to the direction the light is comming from, so the light comming from the side, or not from above, could cause it to 'list". Then there is external damage where the fish has been injured and has damage to its swim bladder. Then last but not least there is bad genetics (inheritance) the fish may have been so inbred that there are genetic faults occurring. There is nothing to be done in the last two instances. Changing the angle of light if that is the problem is the only thing I can suggest.
This condition usually results from poor genetics. There is nothing you can do for the fish and having one eye bigger than the other usually does not affect the fish's health in any way. This just serves as a small reminder to buy from only responsible breeders and not those who are only out to make a profit.
This is just a genetic defect that is quite common in this variety of goldfish do to careless culling of goldfish fry (culling means to select the best looking goldfish fry out of the bunch and to get rid of the fry which have such deformities) However, this is not really something to worry about because it usually doesn't effect the fish and there is nothing you can do to fix this condition.
Your fish is dead or it is very sick and needs to see a vet immediately.
More than likely its dead. Pick it up with the little net to flush and if it squirms and thrashes put it back in the tank, its still alive.
Goldfish as ornamental fish, come in a variety of shapes and sizes, of which the black moor is one.
None, goldfish should only be housed with other goldfish.
No I'm afraid not. As goldfish grow bigger they eat whatever fits in their mouths. But the only species that mixes with goldfish is the weather loach.
it will live
There is a popular bred of goldfish called a black moor. It has an egg shaped body, has protruding globe like eyes and is black in color.
15 years if they are treated properly
Goldfish are not aggressive fish. There must be a reason for a peacfull Black Moor getting aggro. Maybe if you could give me more information I could help with your problem. What size is the tank? How many other fish are in there? What species are they and how large are they? What temperature is the water? Is the tank planted with live plants? What kind of filter are you using? How much water do you change and how often do you do it? What are the fish fed and how often?

Goldfish are opportunistic omnivores and will eat whatever they can. This may include a much smaller fish or a deceased fish.
Black moor fish mix well with other fancy goldfish, but as black moors have poor vision they would be better with other poor vision fish like telescope goldfish or bubble eye as not to have to compete for food finding.
a black moor can eat goldfish flakes and i know is because i have one:-)
Some common breeds of goldfish are: the Black Moor goldfish, the Ryunkin goldfish, the comet goldfish, the common goldfish, the Calico Fantail goldfish, the telescope eye goldfish, the bubble eye goldfish, the pearl scale goldfish and the Oranda goldfish.
