Ginga Rubra Guppy - Poecilia reticulata : Complete Fish Profile & Care Guide
Table of contents
Introduction
Ginga Rubra Guppies (Poecilia reticulata) are a stunning and unique species that are perfect for both novice and experienced aquarists alike. With their striking colours and lively demeanour, these fish add a touch of excitement to any aquarium. In addition, these guppies are incredibly peaceful and make fantastic community tank members, as long as they are not housed with larger or aggressive fish that may see them as prey. While Ginga Rubras do not require any special water parameters, they look their best in a well-planted aquarium.
These guppies have blonde bodies adorned with reddish-pink bar-like blotches that give them a distinctive appearance. In addition, the dorsal and caudal fins of the males have a snake-like pattern, adding an extra layer of visual interest. The males of this species also come in various tail shapes, including short-tailed, bottom sword, and double swordtail varieties.

Sexual Dimorphism
Upon reaching sexual maturity, typically between two to five months of age, distinguishing between male and female Ginga Rubra Guppies becomes a relatively straightforward task. The males of the species exhibit more intense colouration and prominent patterning than their female counterparts. Additionally, males possess a modified anal fin that is both narrower and longer than that of the females. Females, on the other hand, are generally larger than males and display a duller colouration. Notably, females possess a gravid spot positioned just behind the anal fin, which darkens when pregnant.

Natural Habitat
Though Ginga Rubra Guppies were created by the Japanese breeder Kenjiro Tanaka and had no natural habitat, their wild counterparts are typically found in South America's clean, flowing, warm tropical waters. Therefore, if you aim to provide the most natural environment possible for your Guppies, it would be best to replicate these conditions in your aquarium.
Breeding
Ginga Rubra Guppies, like all Guppies, are known for their remarkable ability to reproduce frequently, giving birth to live young every 23 to 28 days. To breed them successfully, it is recommended to keep at least two females to every male in a densely planted aquarium, where they can mate and reproduce naturally.
The males' gonopodium transfers milt to the female, which is used to fertilize her eggs. When the female is ready to give birth, she will display a black gravid spot near her vent. The number of fry in a single drop can vary greatly, from one to thirty or more, depending on the female's age and size.
Initially, the newborns will spend most of their time at the bottom of the tank, consuming their yolk sacs. During this time, they are most vulnerable to predators, including other Guppies and their own mothers. However, once the yolk sac has been fully consumed, they can be fed a diet of baby brine shrimp, powdered fry food, and crushed flake food. Ginga Rubra Guppies will also graze on algae and microorganisms that develop on aquatic plants or aquarium decor. It takes around three to four weeks for males to exhibit their adult colouration and several months to develop the full extent and abundance of colour that characterizes these Guppies.
Diet & feeding
To maintain the optimal health and vitality of Ginga Rubra Guppies, it is recommended to incorporate a balanced and diverse diet that includes high-quality dried foods, such as flakes and granules, along with live and frozen options, such as Daphnia, Bloodworm and brine shrimp. Additionally, vegetable supplements, like shelled peas or blanched spinach, can be provided to ensure a well-rounded diet.
