This period the item is: Shell dwelling cichlids. They are very interesting fishes because they are still in a faze of the evolution. Very interesting because of its behavior is
Neolamprologis similis (BUSCHER, 1992)

This shell dwelling cichlid out of Lake Tanganyika, formerly called Neolamprologus sp.aff. multifasciatus and subsequently because of her conspicuous large eyes Neolamprologus sp. "big eyes", was discovered in the beginning of the ninety's by Ad Konings, who was able to photograph them at two different locations in the middle part of the lake; respectively at Bulu point in Tanzania, and at cap Tembwe in the former Zaire now Congo. A second area of distribution is situated a little farther to the south at the shore of Congo near Zongwe. From this location, discovered by K.H. Büscher also originate the specimen used for the description of the species (1992)
The fish was called so because of the resemblance with Neolamprologus multifasciatus, her distant and legendary nephew. The pattern consists of regularly brown stripes that lay in rather equal distances are visible in the tail fin, the caudal fin, and the most important part of the head as well. One could see in it the negative of Neolamprologus multifasciatus. In the last one, the stripes at the caudal-, the dorsal fin and the forehead as well, fail. The dorsal fin shows a black border and beneath a golden zone, de ventral fins are bluish in the edge. The adult males measure 5 cm, the females 3 cm
In their biotope the animals often dwell in an extended and tight group in de cemeteries of the houses of Neothauma and in cracks in the rocks as well; because they did not finish the evolution till obligate shell dwelling cichlid, holes and caves in the rocks are accepted as a home as well.
The adult animals can be nourished every day with Daphnia, Artemia, Mysis, Cyclops, krill from the freezer of the aquarium specialistshop. At the favourable season oneself also can catch this. Of course self caught and self-frozen nourishment has a higher nutritional value. Also some green nourishment in form of grind pies en carrots mixed up with grind flesh of mussels and shrimps suffice extraordinary. Be careful at feeding enchytrees; make it thrifty considering growing fat.
Unnecessary to say that for sure one must not keep them together with other shell dwellers or even with fishes that in the lake frequent the rock littoral (Julidochromis or other species of Neolamprologus) that without any doubt would dominate them. Without any danger they can be kept together with Paracyprichromis nigripinnis or P.brieni. This would give a very nice view.
