Globe eye / Telescope-eye goldfish

Outward-projecting eyes and a forked divided tail

Metallic red is one regional telescope-form appearance. British standards specify more restrictive eye-shape and colour criteria, while actual eye shapes often overlap with moors. This illustration cannot assign show grade. Unlike celestial forms, upward-looking eyes are not the defining trait and the dorsal fin remains present.

Natural habitat

Wild habitats include rivers, lakes, ponds and ditches, often in vegetated still or slow water; ornamental goldfish are domesticated forms.

Avoid decor that may strike the eyes, fin nippers and excessive feeding competition. Eye size alone does not establish visual ability or health. Swimming and feeding ability vary among forms. Provide filtration, oxygenation and maintenance.
