Telescope

Telescope goldfish are fancy Carassius auratus with prominent eyes that project outward from the sides of the head. The trait is also known as dragon-eye in Asian goldfish traditions, and the black moor is one of the best-known telescope forms. Young fry do not hatch with full eye extension; the eyes become more obvious as the fish grows. Most telescopes have a deep body and paired tail, with varieties appearing in black, red, calico, chocolate, panda, orange-and-white, and other goldfish colors. Eye shape and tail style vary by line, from shorter-finned demekin types to long-finned show fish.

Care revolves around protecting the eyes without treating the fish as fragile ornament. Telescopes see less precisely than ordinary goldfish and can injure their eyes on sharp decor, narrow ornaments, rough nets, or pushy tankmates. They usually fare better with other slow fancy goldfish in tanks with open floor space and moderate current. Feeding should be arranged so they can find food before faster fish clear it away; sinking pellets or gel foods are often easier than flakes scattered across the surface. Breeders select for matched eyes and good body balance, but extreme protrusion can raise welfare concerns if it affects swimming or injury risk.
