During this time, males will have small white bumps known as breeding tubercles on their pectoral fins. The easiest way to sex them is to wait until spawning season which is between April and August. Males are slightly smaller but it’s hard to notice.
Sexing individuals can be difficult, which might be a problem when trying to mate them. Their dorsal and pectoral fins are fairly large, but their anal and tail fins are longer and flowing. This is a common trait of many fancy Goldfish varieties, but it makes them slow swimmers.īlack Moor Goldfish have some beautiful fins which are often the reason that people want this variety, along with the unique eyes. Ironically their eyesight is poor, even with such large eyes.Īnother distinctive feature is their round, egg-like body. The large lenses give them the alternative name of Telescope Goldfish. They gradually get bigger as they age and seem to ‘pop’ out of their head. They first became popular in Korea and Japan in the late 19th and early 20th centuries at Goldfish competitions many fancy breeds came about as a direct result of these shows. Their eyes are the most noticeable part of their body. Black Moor Goldfish are created by crossing a Red Telescope and a Veiltail or Fringetail Fancy Goldfish. Young fish start pale and gradually get darker as they mature. Most are solid black, but some have orange patches across their body. As their name suggests, Black Moor Goldfish are typically black in colour.
