Endler Guppy male red rainbow LT (Poecilia endler red rainbow male) - Tropical Fish for Sale UK

Red is the headline with this Endler. The Red Rainbow male (Poecilia endler) is a line-bred selection named for exactly what it shows: red-led rainbow colouring on a fish of barely 2.5 cm. As a male-only listing, every fish you receive is one of the coloured sex — and at this size, the colour-per-centimetre ratio is very hard to beat in a community aquarium.

Endler care is famously light, and the record here confirms it: easy level, peaceful temperament, omnivorous and unfussy at feeding time, and happy from 22 to 28 °C in water between pH 6.5 and 8.0 with hardness of 8–20 dGH. The recorded minimum tank is 40 litres, and like most of its kind it lives along the top of the aquarium, where red colouring sits directly under the light and works hardest for the display. Plan for a lifespan of around two and a half years per fish.

Also worth knowing before you order: the record cross-references this species as Poecilia wingei, the other name UK keepers will recognise for Endlers — same fish, two labels. The LT in the listing title is simply part of this line's trade name; what matters at the glass is the red. In a green, planted layout it is the highest-contrast colour you can stock at this size, and a group of these males keeps that contrast moving across the top of the tank all day. At a 40-litre recorded minimum it suits proper nano setups as well as larger communities, where its tankmate list below fits most peaceful stocking plans.
