yes they can. the black moore goldfish has telescope eyes as well and so they both suffer from limited vision and competition for food is not as one sided.it is not recommended however to put either in the same tank as a regular goldfish, as their eyesight is normal and they swim faster and so eat a larger percentage of food than the telescope or black moore.
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.
anglesey
it will live
It depends. A feeder goldfish lives to be about 2 years old. A fancy goldfish, (Black Moors, Fantails, etc...) can live to twenty years or more with proper care.
15 years if they are treated properly
goldfish do not live on land
they are found in collection tanks around the world but originally found in China
Not particularly. Black Moors are Goldfish. They are not schooling fish. Each goldfish needs at least 10 gallons of water so if you want to keep a few of them you will need a large tank.
as far as i know yes,unless your fish is aggresive
Goldfish can live in temperatures of 10 to 30 degrees Celsius. Room temperature is also good for goldfish to live in.
Your goldfish will not live "longer" no matter how many or how few you have.
For househeld goldfish, they generally live 6-8 years
