Minimum Tank Size: 1 gallon to 2 1/2 gallon bowl for a trio

Comments:
Nothobranchius rachovii is one of the Soil Spawning Killifish that inhabit the temporary rain pools in Africa.
Males may achieve a size of 2 inches and have predominantly red scales with some aquablue coloration in between, the aquablue color continues onto the fins which are also white tipped. Females may achieve a size of 1.5 inches and are the normal gray Notho female bland .
The eggs may be collected by siphoning the peat moss or coconut fiber thru a fine fishnet or an old piece of ladies panty hose. Squeeze all the excess water out and then store the eggs in a plastic bag (previously marked with the collection date) for 3 to 6 months. Notho fry are very tiny fry, they will need infusoria or green water to start but will begin eating microworms or baby brine shrimp within a day or 2.Change a little water every day, but never over 20%. The fry grow very fast. This is a very difficult Notho for me. It requires a lot of patience and rachovii seems to be very touchy about water quality. Though a difficult fish Nothobranchius rachovii makes up for it with it's unbelivable coloration. A picture cannot do justice to the colors of this fish.
