Difficulty:Easy Max Growth Size: 15-25cm Temperament: Preferred Water Parameters: Temperature:18-27 degrees celsius pH Level:7.2-7.8 General Hardness: Mod- Hard Diet: Goldfish are primarily herbivores despite what many aquarist feed them. Comets and Common Goldfish will take foods such as Brine Shrimp and shelled peas (which are excellent for constipation). However, “meatier” types of foods should be used sparingly, and very high protein foods such as worms should be avoided altogether. Black Moor Goldfish (Carassius auratus) is a popular option among goldfish collectors, due to their unusual appearance, big bug eyes and dark color they have been called some distinctive names like dragon eye goldfish, bug eye fish or boggle goldfish. They are known to be a good option for beginners, thanks to their resilience and ability to withstand a variety of temperatures. The following takes an in-depth look at these beautiful fishes, including where they originated, what sets them apart from other types, how to care for them, and other interesting facts. Easily identified by their short, rounded body and the velvety black hue of their scales, they are also known for their telescopic eyes (think bug eyes) that protrude from both sides of their head. They may have a butterfly tail, broad tail, or ribbon tail. Usually, at their longest, they reach an average of 4 inches, though there have been reports of the breed growing as long as 10 inches in length. However, it is important to note that their appearance does change during their lifespan. During their younger years, the eyes of a black moor Goldfish appear normal, while their scales are lighter and may take on a dark bronze appearance. As they mature, their eyes will protrude and their color will change to the deeper black they are best known for. Finally, as they get older, their black color will begin to fade to a gray or dark bronze color. Their eyes will continue to protrude for the rest of their lives. If you notice that your telescope has a white tint to his scales, it is a good indication that he is sick. Due to their unusual physical characteristics, telescopes are one of the slowest swimming species of goldfish. Care: Again, due to its poor vision, their feeding ability is little since the fish takes time to locate its food. However, it can feed on just anything, flakes and pellets with occasional treats of spinach and lettuce….. Tank Mates: Non-aggressive, moors usually do well when in a group of other goldfish. Because of their different color characteristics, black moors are popular all over the world and an additional benefit is that they enjoy an outdoor pond as they can survive the extremely cold weather
