Small backwater in Alenquer area
46th place in Biotope Aquarium Design Contest 2016
Russia. Aleksandr Dergalyov
Aquarium Volume: 70 L
Fish and invertebrates: Apistogramma cf. agassizii (“Netz”, Alenquer), Nannostomus beckfordi aripirangensis, Gasteropelecus sternicla, Hemigrammus ocellifer, Pomacea diffusa
Plants list: Hydrocotyle leucocephala, Pistia stratiotes
Biotope description: Apistogramma agassizii is the most popular dwarf cichlid in aquarium hobby, which present in lots of geographical races with stable coloration patterns. Some of them appears to evolve in a new subspecies or even a distinct species, and Apistogramma cf. agassizii Alenquer is one of these forms. Being lucky to obtain a pair of F1 offsprings from wild-caught speciments, I try to simulate a small backwater in the left bank tributary of Amazon river. The substrate is a white sand with a lot of leaf litter, pH is about 6 – 6.5 and a temperature is near 26-28 C. Pistia stratiotes, growing on a water surface, shading the midle and the bottom parts of water body. Apistogramma agassizii inhabit the bottom of backwater , where lots of leaf litter creates abundance of spawning cavities; Nannostomus beckfordi aripirangensis, which type locality is also not far from Alenquer, swim in the middle part of a water alongside with Hemigrammus ocellifer, and Gasteropelecus sternicla live under the surface among the floating vegetation.
