#5744 Forest duct of Nun River basin, Bayelsa State, Nigeria

Sponsored by

Nigeria, Bayelsa, Odi

This tank is replicating the slow flowing forest duct of the Nun River basin, in the north of Bayelsa State, Nigeria.

Nun River is the longest (160km) continuation of the Niger River. The Nun River begins near the village of Aboh, where the Niger River splits in two, forming Nun and Forcados, flows through the rain forests, swamps and empties into the Gulf of Guinea. Flooding from monsoon rains lasts from June to September, then the water level drops, and in February, with the arrival of the flood waters from the Niger River, rises again.

Forest rivers and streams of the Nun River basin are home to many species of fish and other aquatic organisms. Although oil production causes serious damage to the local nature, yet in clean rivers significant biodiversity can be found. Mainly semi-aquatic plants grow in places where sun can reach the earth surface through the trees.

Aquarium information

Aquarium description

Set-up date
February, 2022
Aquarium decoration

A large amount of debris are covered the sand layer of the substrate. I used peat moss, JBL Manado, White sugarsand, sand gravels for forming this substance. Numerous driftwood, twigs, branches and roots are present in the aquarium. Water colour is brown for the tannin.

There are lots of hiding places for fishes like Pantodon buchholzi and Pelvicachromis pulcher. African butterfly fishes (Pantodon buchholzi) playing on the top layer of the tank, which is covered with floaters and fern leaves. Kribensis Cichlids (Pelvicachromis pulcher) are playing in the bottom part of the tank. Snails are roaming on the glass, substrate and branches. A mysterious low light river bed atmosphere is created which is same as the forest duct in the Nun river bed.

Aquarium equipment
  • Filtration: Sobo top filter
  • Lighting: spotlight , Fireglow 21 watt .
Fish care

Fishes are habituated with both forzen and dry foods. I feed them Frozen bloodworm, Artemia flakes, Hikari sinking micropellets.

Fishes:

  • Pelvicachromis pulcher (Cichlidae) – 6
  • Pantodon buchholzi (Pantodontidae) – 2

Molluscs:

  • Radix natalensis (Lymnaeinae) – 4
Plant care

African water fern are used for the background, attached with the wood, not place the roots in the substrate. For the middle ground Anubias are attached to the woods and rocks in the tank. Floating plants like Pistia are existing on the surface of the water. Strong lighting is not required for this tank, floating plants, ferns’ leaves provide the shady areas.

Aquatic plants:

  • Anubias barteri var. glabra (Araceae) – 6
  • Anubias barteri var. nana (Araceae) – 7
  • Pistia stratiotes (Araceae) – 10

Wetland plans:

  • Stenochlaena tonuifolia (Blechnaceae ) – 2
Water care

Water change 30% twice a week, I provide a slow moving water condition in the tank. Benifitial bacteria and antichlorine are used at the time of water change.
