Wouldn't it be amazing if you could own a Black Moor goldfish? It's one of the most popular goldfish varieties, kept and loved by millions of aquarists. It is recommended to the beginner aquarist.

Black Moor is a twin-tailed goldfish and has a rounded or egg-shaped body. It's shape is enhanced by the large protruding eyes on the sides of its head. The Black Moor is basically the black version of the Telescope Eye goldfish.

As you noticed, this fish comes in one color - black. The scale coloration can range anywhere from a light grey to a dark black. It's important to note that some Black Moors may not stay pure black forever as they can revert to a metallic orange when kept in warmer water.

The majority of Black Moors are kept in aquariums, not ponds, since their eye sight is far from perfect. Specimens available today have either a broad tail, ribbon tail or butterfly tail.

It gets along well with other non-aggressive goldfish. Black Moors can reach about 4-8 inches in length. The average lifespan of these fish is 10-15 years if kept in well maintained goldfish aquariums. They also eat all kinds of flake, fresh and frozen foods.

You also need to know...

Its protruded eyes cause it to have poor vision so they are subject to injury and infection. They are not good competitors for food because they don't swim very fast. It's quite obvious that you need to keep them with other low-speed goldfish varieties to avoid starving or getting bumped into.

Also avoid adding any sharp objects of plants that can result an injury. The Black Moor requires more care than other varieties with good eye-sight.


Mixing Black Moors along with other egg-shaped goldfish like the Ryukin or Fantail is the best option. All slow twin-tails are great tank mates. Do not mix with faster swimming, single-tailed goldfish varieties.

Better tank mates would be similarly handicapped goldfish like Telescope Eye, Celestial Eye or Bubble Eye goldfish.
