Yssichromis sp. "blue tipped"

Discovered in 1992 by Yves Fermon and Olivier Berthelot off Rusinga Island Lake Victoria. This schooling species feeds upon zooplankton and will also take small insects in the wild. Maximum size is near 10cm for males, slightly smaller for females.

Yssichromis sp. "blue tipped"

Being an open water species, we house our group in a 65 gallon deep tank with a silica
sand substrate. One side of this tank contains a small rock work structure. A few strands of artificial Vallisneria are situated in the middle of the tank. Filtration is provided by an Aquaclear® 300 hang on the back power filter. Weekly water changes of twenty gallons help maintain acceptable conditions. The Yssichromis sp. "blue tipped" are housed with a colony of Platytaeniodus sp. "red tail sheller" of similar size.

This mixture works well as both species are distinct enough that hybridization is unlikely. The rock structure is used by the Platytaeniodus sp. "red tail sheller" as a territorial boundary but has little attraction to the Yssichromis sp. "blue tipped". Neither species is overly aggressive with the other; squabbles are restricted to co specs. The Platyaeniodus sp. "red tail sheller" prefers to remain near the bottom while the Yssichromis sp. "blue tipped" are usually roaming the upper portion of the aquaria. There are occasional bluffing duels between the most dominant males of each species but these are no more than jetting forward in an attempt to back the other up. There is no physical contact or jaw locking that occurs.

Yssichromis sp. "blue tipped" ("tipped blue") as named by Fermon and Berthelot) is a very rare fish in the North American hobby. It is not held in the LV-SSP program so it is up to the hobbyist to ensure its survival.
