Male Royal Green Yellow Guppy 3.5cm
 

The royal green-yellow guppy is a stunning enhancement on the already popular cobra green guppy strain. The art of captive breeding allows for better contrast of yellow against the green body. The allure of their colours, flashy fins, and active behaviour make them such stunning fish for any community aquarium. Royal green-yellow guppies will also make for a
fantastic breeding project as there is plenty of room to introduce different colours or fin structures.

Royal green-yellow guppies are made through selectively breeding the green cobra guppy. There is also a very high chance of yellow cobra guppies being hybridised as well to make these royal green yellow guppies. These guppies have the classic snake-like patterning that runs all through the body and tail. This patterning carries varying shades of green, yellow, purple, and white which make it an incredibly contrasting fish. This strain particularly has a higher focus on the yellow and green colours whilst leaving out the blues and purples seen in standard green cobra guppies. These guppies will look great in almost any aquarium setting whether it is a hardscape-only aquarium or a planted community tank.

Guppies are one of the easiest fish in the aquarium hobby to breed which is why they are such a popular species. These are a livebearer which means the females will give birth to fully formed fry instead of eggs. Females tend to have less green around the fins and body compared to males along with smaller fins however will get larger. The wild habitat of the natural guppy is widespread from South America to Mexico.

Tank Recommendations for Royal Green Yellow Guppy

Being very small and easy to care for fish a trio of these royal green-yellow guppies can be kept in nano aquariums with the minimum being a 40 litre system. A sand or gravel substrate would be fine for these fish as well, a lot of plant growth will also make these fish contrast well but also make for handy locations where guppy fry can grow. Guppies however are considered to be ‘hard water fish meaning they prefer the water to have an elevated PH and are not like a tetra. This higher PH of 7 - 8 can be achieved with a PH buffer or African cichlid lake conditioning salts.

Breeding

Breeding royal green-yellow guppies or any other guppy for that fact is super easy and very different from any other aquarium fish. Where a vast majority of aquarium fish lay eggs, guppies give birth to live young just like mammals. If you are looking to breed guppies it is recommended that there is a ratio of one male to around 3 or more females to make sure that females do not constantly get stressed by the males attempting to breed. When gravid the female guppy will develop a dark black ‘egg spot’ near her ventral fin which is the developing fry. She will then release these in a safe location in the aquarium which is why it is recommended to have a lot of plant cover in the aquarium. Guppies may also eat any fry they find in the aquarium so aquarists often have a ‘grow out aquarium’ however this is not necessary. With these guppies specifically, it is recommended to line breed or regulate the offspring produced as it will ensure that the genetic traits of the patterning, green, and yellow tones are maintained however there is a lot of room to experiment and hybridise to create new and better colour strains!

Suitable Tank Buddies

The royal green-yellow guppy is a very peaceful aquarium fish and males are no different in aggression when compared with females. They are great with a wide range of nano aquarium fish however because of their bright and flashy fins, certain fin-nipping species would be avoided. The other factor is that guppies are fish that need higher PH so keeping them with South American tetras may not be very suitable as these lower PH.

Usually Compatible

Pseudomogil species such as fork-tail rainbows, blue eyes, rice-fish, and nano aquarium fish can tolerate hard water conditions.

Sometimes Compatible

Medium-growing or possibly fin-nipping species. Bettas should also be avoided because of their similar flashy nature to guppies which could lead to aggression from the bettas end.

Rarely Compatible

Large and aggressive species that would prey on the guppies such as oscars, or jaguar cichlids.

Feeding your Male Royal Green Yellow Guppy

The royal green-yellow guppy is very easy to feed once it is settled into the aquarium. It will readily eat a wide range of foods but would prefer to have a floating nano pellet or flake due to its top-dwelling behaviour. Giving them nutritional food with good protein and varied ingredients can result in the mild colours being slightly more enhanced.
