Open encyclopedia reference
Brachyrhaphis rhabdophora, commonly known as the lace brachy, is a poeciliid fish from Costa Rica. B. rhabdophora is similar to B. roseni, with a shorter gonopodium than B. olomina. Rosen and Bailey (1963) considered B. olomina to be a synonym of B. rhabdophora. By 1998 Bussing had demonstrated that these two Brachyrhaphis populations should be treated as different species. B. rhabdophora grows to 6 cm (2.4 in). It has a straight or a slightly arched profile and up to 12 vertical stripes on the sides, which are more conspicuous in males and may be absent in large females. A half of the dorsal fin is yellow or orange, and the fin has a dark margin. The margin of the caudal fin is also yellow or orange; males additionally have a dark band before the margin. The anal fin is yellow with a dark blotch. Females are larger than males and have a stronger build. B.s rhabdophora prefers waters with low to moderate current and is only rarely found in fast flowing waters.
