#544: 200L Biotope Aquascape A underwater forest of Congo river-Yangambi population

Unfortunately your plants are in very poor condition. If you can't maintain them well in this tank you'd be better off not to include them.
— Karen Randall
Well done but it all still looks a bit to fresh. Would also like to see some rocks of different sizes to be added to give it a more natural look.
— Marco Aukes
The rocks used in the biotope do not truly represent what is found in the Congo and were thrown in as an afterthought. The plants also appear to have been added just recently and do not appear as they would in the wild.

Animals 2 male x 12 females Pseudocrenilabrus nicholsi
Pseudocrenilabrus nicholsi is a West African cichlid from the Congo basin (Riehl. etal., 2004). It was originally described as Paratilapia ventralis(Pellegrin, 1928). It has also been known as Haplochromis ventralis, Hemihaplochromis ventralis or Pseudocrenilabrus ventralis.

This fish is found in Africa. More precisely, lies in the east of the central basin of the Congo River (the Ankoro and Upemba Lakes). Type locality for fish is Ankoro (at the junction of the rivers Lualaba and Luvua of Katanga Province, in the south-east of the Republic of Congo (formerly Zaire).Type of P.nicholsi location is outside the Congo Basin forest, but this species was also reported in the heart of central basin area real rainforest. There are no data on the ecology of this species in the Ankoro, but Gosse (1963) has published this information Yangambi populations. In this wooded area, P. Nichols is found in small creeks, tributaries of the Congo River.
These habitats are characterized by sandy substrate and detritus. Plants are few and there but there are Anubias. The clear areas of the water supply can be Bolbitis sp. Light is less and filtered through the branches and roots.
P. nicholsi, is spectacular especially colorful male and which reach a length of 8.5 cm. The female is smaller with about 2 inches and is more diluted colors. . Males have a variety of colors. In general, the male half of the face is bright yellow, which begins to change to blue for the back half of the body. The lips are bright blue. Unpaired fins are represented by red and blue. Pelvic fins are black, edged with white. Pectoral fins are yellow. Behind the gill cover to the back of the fish, there are red spots on the edges of flakes growing in numbers as you go further back on the fish. These cichlids are quite aggressive to their small size. They need to be kept in small groups with more women than men.
. They spawn quite readily in the aquarium. They spawn on the substrate or rocks. They icubatoare maternal mouth. The eggs are taken from the mother immediately after fertilization. Incubation lasts 2-3 weeks depending on the temperature and the chicks are quite small. They need very small food. They are usually good mothers in the first week.
The tank should have many places where they can hide females. Males are aggressive towards females who do not respond to their advances.
Live well at 22 to 25 gr. C and a pH of 6-8.
Materials In this setup I tried to create a floodplain forest of the central flow of the Congo river inhabited by a colony of Pseudocrenilabrus nicholsi. A population Yangambi as was found by Gosse in 1963.
For this I used river sand 1-2mm, mopan African roots and twigs of willow Torsa. At fixing them I used river stones and tried to make a submerged bank. I fixed on the roots and branches Anubias and Bolbitis, plants living in their natural habitat. Back ground I used one textil fabric of ocher colour.
Additional Information I do not fertilize.
