Picta Swamp Guppy (Micropoecilia picta)

Picta Swamp Guppies are relatively small, active, and rare in the aquarium hobby. However, these fish are somewhat delicate, so they are not recommended for beginner aquarists.

Picta Swamp Guppies are a loose shoaling fish in nature, and it would be best to keep two or three females to every male to prevent individual females from being harassed.

These Guppies would thrive in a slightly brackish aquarium on their own or alongside X-ray Tetras. However, you can keep them in a freshwater community aquarium with similarly-sized tankmates like Cardinal Tetras, Black Darter Tetras, Emerald Eye Rasboras, Harlequin Rasboras, Red Neon Blue Eye Rainbowfish, Golden Dwarf Barbs and African Banded Barbs. You may also keep these fish with smaller Plecos, Corydoras Catfish and Dwarf Shrimp.

Picta Swamp Guppies will need a spacious, mature aquarium due to its high activity levels. Although you can find these fish in some freshwater habitats in the wild, the majority have been collected from brackish areas; therefore, they will fare much better and have fewer health problems when maintained in slightly brackish waters in captivity. In addition, these fish are more likely to breed in such conditions.

It would be best if the aquarium were heavily planted with hardy species that can cope well in slightly brackish conditions. Not only will this give the fish somewhere to hide if they feel threatened, but it will also give the females somewhere to retreat to in order to avoid harassment from the over-eager males. It will also provide hiding places for babies. Of course, the aquarium will need to have good filtration, but the water flow should be relatively gentle.

Picta Swamo Guppies have striking red to orange body colours with vivid black markings, making them a highly desirable species. The Males can have various primary body colours ranging from silver to green with yellow, black and blue spots to a red colour with black or yellow spots. The females have silvery bodies with some gold markings or orange around their abdomens.

In the home aquarium, the Picta Swamp Guppy 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.

In contrast, females are larger, fuller-bodied and much plainer coloured than males. Females will also have a gravid spot, whereas males do not.
