PAIR Santa Maria Endler Guppy – Poecilia wingei

Species Introduction

The Santa Maria Endler, scientifically known as Poecilia endler, is one of the most coveted and visually breathtaking varieties of endler’s livebearer. Originally discovered near Laguna de Patos in Venezuela, the endler has captivated aquarists worldwide with its miniature size and extraordinarily vivid colouration. The Santa Maria variety is particularly prized — males display a stunning combination of deep metallic black running along the body, contrasted by brilliant neon orange on the belly and flanks, with flashes of electric blue-green on the tail and dorsal fin. The dorsal fin features a striking orange and black leopard pattern that adds to their exotic appearance. Despite measuring just 2-3cm, these tiny fish pack more colour per centimetre than almost any other freshwater species. Females are larger (up to 4cm) with a subtle golden-olive colouration that complements the male’s vivid display. Sold as a breeding pair, these hardy livebearers are perfect for nano tanks, planted aquariums, and peaceful community setups. Their active, curious nature and constant colour displays make them endlessly entertaining to watch.

Feeding & Nutrition

Santa Maria Endlers thrive on a varied micro-diet suited to their small size. Offer high-quality crushed tropical flakes or specially formulated micro pellets as a daily staple. Supplement regularly with protein-rich live or frozen foods including baby brine shrimp, micro worms, daphnia, and cyclops — these are perfectly sized for their tiny mouths and help intensify the male’s neon orange and blue-green colouration. Carotenoid-enriched colour foods are particularly beneficial. Feed small amounts 2-3 times daily, ensuring complete consumption within a minute or two. Spirulina-based foods and finely blanched vegetables provide essential plant nutrition. Due to their small size and high metabolism, endlers benefit from frequent small meals rather than fewer large ones. A consistently varied diet keeps both the male’s spectacular colours and the female’s health at their peak.

Natural Behaviour & Temperament

Santa Maria Endlers are among the most active, personable fish in the freshwater hobby. Males are perpetual performers, constantly displaying their vivid colouration in elaborate courtship dances, flaring their fins, and darting energetically through the tank. Their tiny size belies an enormous personality — they are bold, curious, and always the first to investigate anything new. Females are calmer but equally engaging, often found grazing on biofilm and algae. As a pair, you’ll observe fascinating social dynamics with the male frequently displaying to the female in a rapid, flickering dance that showcases every colour on his body. Endlers are entirely peaceful and never bother other species, making them ideal community members. They occupy primarily the mid to upper water levels and thrive in planted environments where they can weave through vegetation. Their constant activity and colour displays make them one of the most entertaining fish to keep.

Tank Setup Guide

Santa Maria Endlers are perfect for nano tanks and planted aquariums. A minimum 30-litre tank is ideal for a pair, though a larger tank allows you to enjoy a breeding colony. Use fine gravel or sand substrate with dense planting — Java Moss, Hornwort, Guppy Grass, and Anubias Nana are all excellent choices that provide cover, grazing surfaces, and shelter for fry. Floating plants like Duckweed, Salvinia, or Amazon Frogbit create shaded areas that endlers appreciate and help diffuse lighting. Gentle filtration is essential — use a sponge filter or adjust flow to minimum, as these tiny fish prefer calm waters. A small heater maintaining 24-28°C ensures comfort. Good LED lighting on a 10-12 hour cycle showcases the male’s metallic colours beautifully. Dark substrates provide stunning contrast against the neon orange and blue-green markings. Weekly 20-25% water changes maintain pristine conditions for these jewel-like fish.

Compatibility Guide

Santa Maria Endlers are supremely peaceful and compatible with a wide range of similarly sized, non-aggressive species. Excellent tank mates include Ember Tetras, Celestial Pearl Danios, Pygmy Corydoras, Chili Rasboras, Otocinclus, Cherry Shrimp, and Amano Shrimp. They also coexist beautifully with other endler varieties and can be kept with fancy guppies, though interbreeding may occur. Avoid housing with any fish large enough to view them as food — their tiny size makes them vulnerable to even moderately sized tank mates. Avoid fin-nippers and boisterous species that could stress them. A species-only nano tank is also a wonderful option, allowing you to enjoy their natural behaviours and potentially raise fry in a dedicated endler community.

Breeding Information

Sold as a breeding pair (one male + one female), Santa Maria Endlers are prolific and straightforward to breed. As livebearers, the female gives birth to fully formed, free-swimming fry after a gestation period of approximately 23-28 days. Broods typically consist of 5-15 tiny fry, which are miniature versions of the adults. Dense planting, particularly Java Moss and floating plants, provides essential shelter for newborn fry, significantly improving survival rates. The fry grow quickly on a diet of crushed flakes, baby brine shrimp, and micro worms. Male fry begin showing colour at around 3-4 weeks, reaching full colouration by 8-12 weeks. To maintain the pure Santa Maria line, keep them separate from other guppy and endler varieties. With good conditions, you can establish a self-sustaining colony that provides endless colour and activity in your aquarium.

Health & Wellness

Santa Maria Endlers are remarkably hardy for their diminutive size, but consistent care ensures they thrive. Regular water parameter monitoring — temperature, pH, ammonia, nitrite, and nitrate — is essential. Their small body mass means they are more sensitive to water quality fluctuations than larger fish, making consistent conditions and regular water changes crucial. Watch for common issues including ich, fin rot, and internal parasites. Warning signs include colour fading, clamped fins, lethargy, or loss of appetite. The male’s colour intensity is an excellent health barometer — vibrant colours indicate a healthy, content fish. Quarantine any sick individuals promptly. With optimal care, endlers typically live 2-3 years, with males maintaining their spectacular colouration throughout their lives.

Acclimation Process

Due to their small size, careful acclimation is especially important for Santa Maria Endlers. Float the sealed bag in your tank for 15-20 minutes to equalise temperature. Add small amounts of tank water to the bag every 5 minutes over 45 minutes — the longer acclimation period accounts for their sensitivity. Transfer using a fine-mesh net and never add transport water to your tank. Dim lights for several hours and skip the first feeding. Over the following days, you’ll see the male’s colours intensify dramatically as he settles in and begins displaying. Provide plenty of plant cover — endlers feel most secure among vegetation and will reward you with bolder behaviour and brighter colours when they feel safe.
