Ophthalmotilapia boops Kipili "Neon Streak"
Origin and locale/variety: Nkondwe, Kipili--Tanzania, Lake Tanganyika, East Africa
Size: Adults are usually 3.5 to 5.5 inches in aquarium environment.
Sex differences: Males show dark purple/black bodies with a neon blue/white streak from the middle of the torso through the caudal. Males also develop large yellow lapets on the tips of the ventral fins and may obtain long filaments. The females range from silver to dark gray depending upon mood. Females may also show remnants of the yellow lapets.
Aquarium behavior: Ophthalmotilapia boops may be one of the few featherfins to constantly hold full color. Very rarely is the dominant male seen in less than full breeding dress. Ophthalmotilapia can be kept in either community set-ups or single species aquaria. In the community environment, their keeper will quickly know where the dominant male decides to call home. A fairly large aquarium is recommended, as they are somewhat territorial. This fish is active and spends much time and energy showing off to conspecifics.
Aquarium diet: O. boops readily accept most foods: flakes, frozen, pellets, and live. A combination of flakes, frozen, and live is recommended. This fish also enjoys grazing algae from the edges of rocks.
Observed spawning habits: The dominant male entices females into his territory. She will enter when she is ready to spawn. She will lay her eggs and the males will begin the fertilization process. As the male is fertilizing them, she picks them up to begin a mouthbrooding session that can last up to a month.
Other information: Ophthalmotilapia boops Kipili is infrequently available. Besides being in great demand, the fish enjoys constant attention and is the topic for many conversations among Tanganyikan enthusiasts.
