- Original genus Lamprologus
was divided into genera Altolamprologus, Lepidiolamprologus,
Neolamprologus, Lamprologus and Variabilichromis.
Genus Neolamprologus is definitely the most numerous
one. It includes further 45 carnivorous species. Most of them are
litofilous cichlids which lay eggs into various rock shelters. A few of
them have chosen, during their phylogenetic evolution, empty shells of
Neothauma tanganicense gastropods as their shelters.
- The fish usually live
in pairs. Both parents look after their offspring for a few months. Egg
evolution lasts approximately for 70 hours before embryos hatch from them.
For further 6 – 7 days, larvae consume the yolk sac. After absorbing it,
they start consuming exogenetic food and start hunting for prey. Most
species are territorial. That´s why it is advisable to breed fish in pairs,
or in a group which corresponds the size of the tank to avoid fights,
which may lead to killing of a weaker fish.
- Neolamprologus buescheri
- N. buescheri-
This species lives in a few forms in southern part of the lake in the
depth of 20 – 40 metres.
- There is rather a small number of
offspring from a spawn ( 10 – 20 fish ) if the spawn stays with the
parents. However, fish lay many more
eggs. For example, I once
found 65 hidden eggs in a shelter when cleaning the tank. I put the eggs
on a mat into the element tank so that their parents
should not eat them, as I had moved the stones. I managed to breed all
the offspring. Parents seem to reduce the number of eggs and larvae to
the reasonable level. It is, nevertheless, not true about
multigeneration breeding from a single pair. In such a case, there are
about 100 offspring of different sizes swimming aroud the parential pair.
has got two known forms which are named after the area where they live.
These are Kavalla and Ubwari forms. Both of them live in a
rocky biotope about 20 metres bellow the surface. Ubwari males, which
I breed, usually grow up to 12 cm of length.whereas females grow up to 9 –
10 cm. The fish started to spawn as late as at the age of 3. At that time,
I was starting to think about whether I should include them among the
species I failed to propagate or not. Each time, I managed to breed 30 –
50 fish from one spawn.
– I have been breeding this species for many years. Unfortunately, I cannot
say I have found the proper way to reproduce them. It is true that I have
had some breedings, but I am not able to specify what makes them spawn. That
is the fact which makes me continue to study this species. They grow up to
10 cm of length and they are well known for their inner species
aggressiveness. Therefore it is really necessary to breed them in pairs in a
larger tank with, at least, several shelters. To breed them in a group, a
breeder needs a 2 metre long tank. However, he will not be able to avoid
cases in which a weaker fish is killed.
pectoralis is one of the lake´s jewels, but it is
one of the most dangerous killers at the same time. These are the reasons
why the species is rather rare in breeders´aquariums and on offer lists of
importers. It lives, as N. nigriventris, in deeper rocky zones of the
lake. The size of adult fish is 10 cm. My longest male was 13 cm long,
female 11. Large fan shaped pectoral fins are the most beautiful feature of
the species. It is necessary to use a tank long enough with enough shelters
to breed the fish in.
- N. furcifer
is a very interesting fish belonging into the genus. It lives in the whole
lake in areas formed by huge rock blocks. Males grow up to 17 cm of
length, females 13 – 14 cm. It is essential to consider the fish size when
chosing the tank ( It should be 400 litre and larger). This species tends
to suffer from problems with their gas vesicle ( mainly when transported
). As a result, we can often come across a fish swimming in a strange way.
- Genus consists of 3 colour forms. There are two northern yellow fish - one
of them living by western Congo bank of the lake, the other by eastern
Tanzanian bank. The third fish is blue, lives in the south and is known as
„Sambia“. The speciality of this species is a high reproductivity of
yellow forms while the blue form has not been reared in aquarium conditions
yet. Despite the fact that it has been imported for almost 25 years.
