Daisys Blue Ricefish (Oryzias woworae)

The Daisy's Blue Ricefish are a very peaceful, active schooling fish that are perfect for the nano or planted aquarium. However, due to their small size, these fish are not recommended for the general community aquarium.

The Daisy's Blue Ricefish must be kept in schools of 6 or more individuals. The reason for this being not only will they display their best natural behaviour and colouration in large schools, but they will also pay little to no attention to other species.

If you would like to house these with other fish, small species such as Microdevario, Sundadanio, Trigonostigma, Pygmy Corydoras and small Catfish such as Otocinclus would be the best choices. These Ricefish will also do fine with Dwarf Shrimp. However, if you intend on breeding your Ricefish, then you should ideally maintain them alone.

These Ricefish are very hardy and adaptable; however, they do require clean, well-maintained water to thrive. These fish will also exhibit their best colours in a well-planted aquarium with a dark substrate, especially where floating plants are present. As long as these fish have plenty of coverage, they are a highly outgoing species.

Male Daisy's Blue Ricefish have a steel blue body bordered with bright red stripes on the ventral surface of the head and body as well as on the pectoral fins, the caudal peduncle, and on the dorsal and ventral portions of the caudal fin. The females also have these reddish outlines; however, they have a yellow body colour instead.

In the home aquarium, the Daisys Blue Ricefish will readily accept most good quality dried foods such as granules, flakes and sinking pellets. These modern food products have been developed to provide all adequate nutrition to maintain your fish's health and dietary requirements.

Providing additional foodstuffs such as live, frozen, and freeze-dried meals such as bloodworm, daphnia, and tubifex once or twice a week will provide additional benefits to your fish's health and well-being but is not a must for this fish.

It should be noted that bloodworms should only be given as an occasional treat and should not be used as the staple diet as they are difficult for fish to digest and can potentially cause blockages.

This fish is an omnivore in the wild, meaning it will consume some vegetable matter. Although most modern fish foods take this into account and include them in their products, you can still supplement your fish's diet with blanched vegetables such as spinach, broccoli, and zucchini. Ensure you do not overfeed your fish and remove any leftovers the following day.

Sexual Dimorphism

It is very straightforward to distinguish the male from the female Daisy's Blue Ricefish. Mature males are slimmer, far more colourful and have longer anal and dorsal fins, whereas females are more plumper with plainer body colour.
