1. Black Moor Goldfish
The black moor is a telescope-eyed variety of fancy goldfish that has a characteristic pair of protruding eyes. It is also referred to as popeye, telescope, kuro demekin in Japan and dragon-eye in China.

Description of black moor

Black Moors (Carassius auratus) have deep bodies and long, flowing finnage, along with characteristic protruding eyes. They are veiltailed and possess metallic scales with a velvet-like appearance.

Young Moors resemble bronze fantails. Their black coloration and eye protrusion develop with age. They can grow up to a length of 10 inches, but may not lose their velvet-like appearance with increasing age. Black demekins may also revert to metallic orange when exposed to warm water temperature. The fish can range in coloring anywhere from a lighter grey to a dark black, but most Black Moor goldfish don't stay pure black forever and many Of them change colors from a rust color underbelly to orange splotches.

Black moor goldfish are popular because they are hardy fish, and because their black color sets them apart from the more common gold color. Goldfish are typically easy to care for, surprisingly, black moors in particular are able to withstand a wide variety of temperatures but cannot withstand extreme temperatures.

Special Care of black moor
Black moors have poor vision, therefore mixing them with more active varieties of fish is not recommended. Because of their delicate eyes, an aquarium without any sharp and pointed objects is preferred. If a Black Moor's eyes are damaged, you should quarantine or take the fish to the vet. The Eyes might heal but they will not look as good and most likely be blind. So take caution. They are sensitive to prolonged exposure to low temperature levels. Black moors are very susceptible to dirty water and can die if not kept in very clean water. It is recommended that they be kept with fish with similar sight handicaps, or given more time to get to their food as it could take them so long that they lose out on their meal to other, faster fish in their environment. If kept with other goldfish it will school with them. Black moors will dig in aquarium bottoms, often leading to uprooted plants and decorations. Optimum aquarium environments have a neutral pH and water temperature of 65 to 72 °F (18 to 22 °C).[citation needed]

Like most goldfish, black moors are prone to overeating, sometimes causing death. These fish should not be overfed.

2. Bubble Eye Goldfish
The Bubble Eye is a small variety of fancy goldfish with upward pointing eyes that are accompanied by two large fluid-filled sacs. It is a dorsal-less fish, and good specimens will have a clean back and eye bubbles well matched for colour and size.

Description of bubble eye
The Bubble Eye normally has an evenly curved back that lacks a fin. The pair of large pouches of skin attached under its eyes jiggle as it swims. Bubble Eyes have metallic scales and they are similar to the celestial eye goldfish. The eyes of the Bubble Eye goldfish are normal in the young fry, but will start to develop eye bladders three months after hatching. Like ranchu, the bubble eye goldfish lacks in dorsal fin and has a double tail. They normally grow up to 6 to 8 inches in length.

Special Care of Bubble Eye Goldfish
The bubbles are fragile and the fish should be kept separately from boisterous types and away from sharp tank decor, although the bubbles will regrow if punctured. Given proper accommodation, the bubbles do not disadvantage the fish and they become very tame. It is known as suihogan in Japan.

8.Lionhead goldfish
Description of lionhead

The tremendous hood or headgrowth and fat cheeks of lionheads give them a facial appearance similar to canine puppies. The "wen" (Chinese term for headgrowth) fully covers the head, cheeks and gill plates of the fish. Furthermore, Lionheads have short but deep bodies, and relatively straight or evenly arched backs without dorsal fins. The finnage, in general, is short. Breeding standards require that the lionhead’s anal fins are paired, the double tail fin should not droop, and its upper edges should be held away from the body. The tail of a traditional lionhead can be fully separated, partially separated, or webbed. The tail should also meet the caudal peduncle (the area where the body joins the tail) in a fashion that is almost perpendicular to the body. The caudal peduncle is ideally broad, allowing the tail to open when the fish swims. The back of the proper lionhead is quite broad to support the placement of the raspberry-like hood. Hood development may vary but is more pronounced in males. The hood normally takes a year to develop in young fry. Mature male lionheads periodically shed patches of their headgrowths.

Lionheads can grow up to 6 inches (15 cm) in length (including finnage) and may have metallic, nacreous or matte scales. They come in a variety of coloration.

Special care of lionhead

Lionheads are sometimes sensitive to low water temperatures.
