Endlers (Poecilia wingei) are an adorable tiny nano livebearer that come in a huge variety of eye-catching colour patterns. They are completely peaceful, but having a higher ratio of males than females can lead to stressed out/harassed females because the males will endlessly try to get their attention so it is recommended to have 2 females per male. Males are significantly smaller than females, being only 1" at adult size- females can grow to be nearly twice the size and typically are drab/colourless- although a few females may display a slight shimmer/colour just on their fins.
