Tropheus polli (G.S.Axelrod,1977)
Tropheus polli is one of the seldom Tropheus-types with in mature state a kind of a pattern with stripes. With the other specimen the striping pattern is characteristic for the juveniles. Farther characteristics are the special pattern of stripes and the form of the fins. The tailfin shows resemblance with a swallow's tail. Tropheus polli is a little bit larger than the other specimen;ca. 16,5 cm is quite normal for a mature man. Grown up man are solid gray or brown, with some olive-green reflections. The body and the fins of the female and the juveniles are olive-green green or brownish and on the sides there are eight white-yellow diagonal bars between the gill covers and the root. A nineteenth bar is on the outer part of the gill covers. You often see also stripes on the snout and above eyes. The last one mostly runs across the jaws until the throat. The eyes are light blue with a black upper edge. On the gill covers there is a black spot. In the soft part of the dorsal and anal fin and in the tailfin too there are little spots and orange stripes. Before this species was known at the name the "Wimpelmoorii". On the determination the electronic microscope was used to examine the teeth in detail and a description sometimes is illustrated with remarkable pictures of it. G.S. Axelrod declares that the colors are no criterion after all there exist several colorvariants of the specimen. Others on the other hand estimate the colors and also the place of the colors of great importance at the ascription just like the place where they were caught can play a role. In this way the dominant red color Characteristic for the southern variants of Tropheus moorii. Possible the electronicmicroscopes-can-method give interesting insights. I assume that for the moment we have a useful classification; however the last word about that certainly is spoken not yet. All the more because of a number of splendid specimen, under thereunder f.e. the striking Tropheus "Bulu Point" are still waiting for an official description.
Tropheus polli occurs in the littoral zone at a depth from 6 until tot 10 meters in the mid of the Eastern coast apposite of the Lukuga river and Kalemi. It seems to be that also along the Southern coast of Bulu Island and around Bulu Point there haunt a population.

When one wants to purchase a population of a particular specimen of Tropheus he is right to read up on the subject. In spite of the price one does not by Tropheus by two or three but by fifteen or twenty. For preference young or juvenile specimen. Therefore one tries to find a trusted and experienced fancier. One has the best chance for it at one of the numerous fairs that are frequently organized in Belgium and the Netherlands nowadays. In advance of course one has prepared a spacious aquarium for them. At first we don't keep them together with other fishes. They have to get an opportunity to explore the tank, to get acquainted with each other in the way that a real social group is formed in which a specific order rules. If one acts in an other way, the chance for disappointment is enormous great. The fact is that they are extremely aggressive. And only in a group it is to be suppressed well on one side and on the other hand it forms the binding element in the group. Only in this way they are a sight for sore eyes of the aquarist who spends many hours studying the behaviors. Each individual concurs his own place on the social ladder. At only one or two individuals that of course is out of the question. Only by taking of one or two specimen the order is disturbed and dogged fights will burst out. Some fish will be the victims of it. The order in the tank at home is also quickly determined when only one fish of the new purchased ones will be left. Joung fishes, on the other hand, are to be acquainted to each other more easily. They will start to establish in a natural way which one will be at the top of the social order and which one will be the last. Of course every individue will seize each opportunity to end in a higher place in the order. However they know each other so well that this will never end in a slaughter but in some sham fights in which it will sometimes come to pulling each other with the beaks If this fighting becomes to dogged, some of the fishes higher up in the order will come quickly and end the fight. Every fish will know its place. Just this social behavior makes the group of tropheus to a lasting joy for the owner. The bigger the aquarium the better. Stones put in it not only serve the esthetic element, but the interacting of the animals also. In this way they are able to escape their rivals by hiding behind or underneath the stones.
