Platinum Medaka Ricefish (Oryzias latipes var Platinum)

Platinum Medaka Ricefish are peaceful community aquarium fish always on display with superb colouration and is the perfect companion for any temperate aquarium. In an aquarium, they won't bother anyone, but if kept in a species-only setup with floating plants, they'll quickly multiply.

It is common for Platinum Ricefish to live in groups. School is the term used to describe these groups. In spite of this, they sometimes move alone or in pairs. Ricefish behave similarly to other small community fish species in a very serene manner. Fish that are proportional to their size are, therefore, preferable. Guppies, Seluang fish, pseudomugil, Corydoras Catfish, and Neon Tetras are all excellent choices. It is also possible to add shrimps and snails freely.

It would be better to avoid putting Ricefish with aggressive species. It is common for ricefish to have excellent relationships with their relatives. It is not unusual for males to fight aggressively for female attention, but these fights do not often lead to severe injuries.

Platinum Ricefish are incredibly hardy and are known for their ability to survive even when the surface of their pond is frozen. Ricefish can survive in almost any environment, but they cannot live in dirty or polluted water, so you must keep their aquarium clean and well-filtered. It is, therefore, much healthier for them if you regularly change the aquarium's water.

Creating a natural environment for Platinum Ricefish in your aquarium is recommended, just as you would for any other freshwater fish. Before adding Ricefish to your aquarium, ensure it has been adequately cycled. Give them a comfortable habitat by using driftwood and aquarium plants and providing them with hiding places if needed. Live aquatic plants are not harmed by Rice Fish.

It is best for them to live in an environment that is well-lit. Platinum Ricefish naturally live in rice paddies with shallow water, so they receive a lot of sunlight. Due to their excellent mobility, these fish can quickly jump out of the aquarium, so the lid must be sturdy.

Platinum Ricefish are pale white and shimmery, with their only dark spots being their black pupils. Despite the fish's size, the iridescent scales occasionally appear blue and sometimes metallic silver, flashing as it swings and is incredibly bright.

In the home aquarium, the Platinum Medaka 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

Platinum Ricefish can be sexed easily as adults. Generally, females are larger than males and have much fuller bodies. In contrast, The males are slimmer, usually much more colourful than their female counterparts and have extensions on their anal fins, which can become spectacular in some species.

The genital papilla is a small pointed bump located just in front of the anal fin of males. Females usually have a relatively flat area with only a small, rounded protrusion. Female Rice Fish can be seen swimming around with clusters of eggs in a community tank in the morning, which is one of the most exciting things about this fish.
