Top Five Rasbora Fish for a Tropical Freshwater Aquarium

Rasboras, along with danios and barbs, are in the Cyprinidae family of tropical fish. They are popular fish to keep in a home aquarium. They are characterized by long, narrow bodies with deeply lobed tail, or caudal, fins.

Red-Tailed Rasbora

The red-tailed rasbora is a smaller variety from this tropical fish family. Growing to a maximum length of two inches, it has a slim body with a yellow cast to it. The lower half of the body is primarily silver and there is a darker lateral line running from behind the gills to the tail. The tail has a reddish tint. It is an active fish and prefers an aquarium with plenty of space to swim.

Eye-Spot Rasbora

They eye-spot rasbora is so named because of the dark blotch on the dorsal fin. This spot has a white edge to it, making it look somewhat like a large eye. The rest of the fish is metallic gold in color on the top half, and shimmering white on the lower regions. It grows from two to three inches long. This rasbora variety prefers to be kept in schools of its own kind. It enjoys well planted tanks.

Scissortail Rasbora

The scissortail is a three to four inch long fish with a bright silvery color. The tail fin has delicate black and white marks and is deeply forked. When at rest, the fish's tail twitches in a motion much like the blades of a scissor.

Harlequin Rasbora

One of the more popular of all tropical freshwater fish types, the harlequin rasbora is named for its bright coloration. This fish has a wider body than some of its relatives. At only one and a half inches long, it is also smaller. The bottom of the harlequin rasbora's body is silvery, the top and tail golden in color, and there is a large black blotch on the second half of the body. The dorsal fin also has a vivid yellow spot against a white background.

Clown Rasbora

Another brightly colored rasbora is the clown rasbora. This fish grows to a length of three to four inches and prefers to school with others of the same species. It is a rare fish to find in aquarium stores, but its showy scales are worth the hunt. The body scales are pinkish orange and two dark spots show behind the gills and on the abdomen. The fins and tail are yellow.
