• ish-green and are edged in black. They have a few of the reddish body spots at their base and more faintly, also along the trailing edges of these fins. The caudal fin is not as fan-shaped as those of related rivulids, the rear edge being more straight than circular and quite variable in pattern. Generally, it is black along the top and bottom edges. Beginning at the caudal peduncle, just below the top black edge, is a yellowish-green horizontal streak which fades into the dark-gray central region below. The end of the tail fin has a vertical white band between the top and bottom black edges and is the most eye-catching feature of the species. The males originally imported into this country in 1956 had a bright orange streak instead of the white one, hence the popular name, "goldentail rivulus." The author has seen males which had a completely-black border around the entire caudal fin, the center being a dark gray. They were found in a wild shipment of normally-colored males. Females are gray in color, overlaid with black spots that gather in places all over the body, presenting a mottled appearance. Belly region, throat and jaw are pink-white and the typical rivulus ocellatus is visible on the upper caudal peduncle. The dorsal and caudal fins present the same mottled pattern, the ventrals are clear and the anal fin is the same as described for the male but muted in coloration. Keeping the species is no problem as they will greedily accept dry foods, chopped beef heart, shrimp, etc., as well as live foods. They do well at temperatures between 68 to 85° F and very seldom do males viciously drive the females during spawning. Water conditions can vary widely. The author has kept them in water varying from 6.2 to 7.3 pH and 0 to 9 DH with no apparent discomfort. They make good community tank killies with the larger top-spawners such as Aplocheilus lineatus, Pachypanchax homolonotus, P. playfairii, Epi- platys sexfasciatus, etc. They are, however, occasional jumpers so their tank should be completely covered. Credit goes to Albert J. Klee for introducing the scientific name of this species to the hobby when in 1959, his search for its taxonomic description proved fruitful and it was found to have been described by Fowler in 1941. Spawning R. milesi is easy although the breeders are avid egg- eaters. Unless many thick mops are used, don't expect more than
