They may have a butterfly tail, broad tail, or ribbon tail.

  • 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.


Black Moor Goldfish In Garden Pond?

A garden pond is a wonderful addition to your outdoor living space. When it comes to what types of fish you can put in it, you do have plenty of options. Most commonly seen in garden ponds are Koi fish as they are hardy, handle cold weather well, and live for many years. Not many people consider putting goldfish in their ponds but they make a wonderful option. Black Moor goldfish, in particular, make a great addition to any size pond, big or small.

Black Moor is very enduring fish. While some may opt to bring them indoors for the winter, it is not necessary. They can handle temperature changes with the seasons by adjusting their metabolism accordingly. When it is warm out, they raise their metabolism rate thus eating more and growing larger. When it is cold out, they drop their metabolism to conserve energy and to need less intake of food.

Speaking of food, Black Moor are omnivores which means they eat plants and animals. This is actually beneficial for sustaining a balanced ecosystem within your pond. Plants will not grow out of control and any bugs that fall in will be used as a great natural protein source for your fish. Having a balanced variety available in the pond year-round is key to keeping them happy and healthy.

Proper socializing keeps these fish from getting bored. You will want to have at least 3 Black Moors in a single pond. They can grow to be roughly 8 inches so even a smaller pond should be able to accommodate all 3 nicely. You can put other fish with them in the pond because of their friendly nature but it is best to stick to certain kinds of fish to prevent injuries. The eyes of a Black Moor are very susceptible to damage because they stick out so pairing that with other visually challenged fish is best. Any kind of telescope or bubble-eye goldfish will go nicely with them. This will prevent issues with food fighting and starvation as well.

As for decor, plants, and stones; Keep it simple! Avoid using anything sharp in the water. As mentioned above they have poor vision and can easily cut their eyes on anything that is too pointy. Smooth rocks and spike/thorn free water plants will be good. Having a pump to circulate the water is not required but it will help keep the tank thriving and the fish happy.
