Nothobranchius rachovii

Alternative names

 * Bluefin Notho,

Sexing

 * Males have more vivid colouration and longer finnage than females.

Tank compatibility

 * These fish should only be kept in species tanks. Males can be quite aggressive towards one another, if two are to be kept you'll need a very spacious tank. Keep females in the ratio of 2-3 females per male as the females will be heavily pursued.

Diet

 * These fish should not be fed dried foods if it can be avoided, they do much better on live/frozen food such as brine shrimp, daphnia and bloodworm.

Feeding regime

 * Feed once or twice a day.

Environment Specifics

 * These fish need quite a specific set up in order to be kept successfully and breed. They need a mature tank with a dark substrate, preferably peat moss, as well as dense planting and bogwood décor. Floating plants will help diffuse light as they do not appreciate bright lighting. A tight-fitting cover is a must as these fish can jump.

Behaviour

 * An annual Killifish that can be nippy and territorial

Identification

 * A very attractive fish, its body is red-orange in base colour, overlaid with iridescent blue scales. The dorsal, anal and pelvic fins are blue with red markings. The caudal fin has a thick orange band and edged with a black band. There are selective-bred colour variations seen also.
