Aphyosemion bivittatum (twostripe lyretail, two-banded killi, red lyretail) is a species of freshwater fish belonging to the family Aplocheilidae. It is found in rivers in southeastern Nigeria and southwestern Cameroon. [2] It was originally described as Fundulus bivittatus by Swedish zoologist Einar Lönnberg in 1895. The holotype was discovered near a waterfall in the Ndian River in Cameroon and currently is located in the Stockholm Museum. [3]
A. bivittatum has an elongated, brightly coloured body with two dark bands made up of red spots running along each side, with the colors varying between populations. [4] Individual males are commonly found with golden-brown dorsal surfaces, bluish sides, and golden ventral surfaces. [4] The males have a maximum body length of approximately 5 centimetres (2.0 in) and have brightly marked, tall and pointed anal and dorsal fins that are yellow to pastel green with red edges. [4] The caudal and dorsal fins are green with red spots and bright yellow tips. [4] It has 10–13 spines in its dorsal fin and 12–15 in its anal fin. [5]
The species is found in small calcium rich steams in the coastal rainforests of southeastern Nigeria and southwestern Cameroon. They are benthopelagic, meaning they float just above the riverbed. [1] They prefer water with a pH of 6 to 6.5 and temperature of 22 to 24 °C (72 to 75 °F). [6] [2]
