Red Dragon Halfmoon Guppy Pair (Poecilia reticulata)

Red Dragon Halfmoon Guppy Pair: one male and one female

Red Dragon Halfmoon is a fancy guppy trade form with a patterned body and broad red tail. “Halfmoon” describes the trade form, not a guarantee that every fish opens its tail to a measured angle. Individual colour, markings and fin shape vary with age and condition; females are generally plainer.

For a different retail trade form, compare the separate Blue Dragon Guppy Pair or Red Tuxedo Koi Red Nose Guppy Pair. These are form comparisons, not a breeding-match or tank-mate guarantee.

The guppy (Poecilia reticulata) is a peaceful livebearer originally from northern South America and the southern Caribbean, including Venezuela, Trinidad, Barbados and the Guianas. Fancy strains like this one are aquarium-bred for colour and fin shape. FishBase gives about 3.5 cm for males and up to 5 cm for females.

What you receive

Choose the size, then the quantity. One quantity is one pair — one male and one female — in the size you choose: 2–3 cm, or the larger 3.5 cm. Order two for two pairs. The male shows the full strain colour and long tail; the female is plainer, with the colour mainly in her tail. Choose from the current size selector; availability can vary.

Reference images are not the individual fish received and do not certify breeding history. Fancy guppies vary in colour intensity and tail shape; the retail pair is one male and one female, not a proven breeding pair.

Aquarium and water

A mature, cycled aquarium of 60 litres or more suits a small group; use the tropical aquarium setup guide to plan gentle flow, open swimming space and fine-leaved or floating plants. Guppies prefer harder, slightly alkaline water: a routine 22–28°C, pH 7.0–8.0 and 9–18 dGH, inside the FishBase, Seriously Fish and OATA ranges. Keep nitrate low with regular partial water changes. If you add more guppies later, two or three females per male reduces chasing.

Feeding

Feed a quality small flake or micro-pellet once or twice a day, with small frozen or live foods such as Daphnia, brine shrimp and bloodworm a few times a week. Offer only what the fish clear in a couple of minutes.

Tank mates and behaviour

Peaceful and ideal for community aquariums with other small, calm fish that like similar water: platies, mollies, Corydoras, small rasboras and peaceful tetras. Avoid fin-nippers such as Tiger Barbs and larger fish that could eat them; long-finned males are slow swimmers. Most tank mates will eat guppy fry.

Follow the arrival sequence before releasing the fish

Tropical Fish Co’s delivery and Live Arrival Guarantee policy explains the packing and arrival procedure. Livestock is hand-bagged in pure oxygen and placed in an insulated poly box, with a heat pack when the weather calls for it. Someone must be at the address to receive the parcel because live animals cannot be left unattended.

1. Receive the parcel in person and start filming before opening it. Show the parcel still sealed with the outer box visible.
2. Open the parcel in one continuous take. Keep filming until the fish can be seen inside the sealed bag before anything is disturbed.
3. Float the bag for 20–30 minutes so the temperature equalises slowly.
4. Do not pour the bag water into the aquarium. Release the fish without adding transport water to the established system.

If a Live Arrival Guarantee claim is required, contact us on the same day with the order number and the continuous unboxing video. Before the parcel arrives, confirm that ammonia and nitrite read zero and that the aquarium matches the water values on this page.

Frequently asked questions

What do I get with one quantity?

One quantity is one pair: a male and a female Red Dragon Halfmoon Guppy. Order two for two pairs.

Do the male and female look the same?

No. As in all fancy guppies, the male carries the full strain colour and the long, showy tail; the female is larger, plainer-bodied and shows the strain colour mainly in her tail and fins.

What water do guppies need?

A routine 22–28°C with pH 7.0–8.0 and 9–18 dGH, in a mature, cycled aquarium.

Will they breed?

Guppies can breed, but a retail male-and-female pair is not a guarantee of pregnancy, fry production or a bonded breeding pair. Dense plants offer shelter if fry are produced.
