Zebra acara (Ivanacara adoketa) is a species of cichlid from Rio Uaupes and Rio Preto, two side rivers of Rio Negro in Brazil. This species can reach a length of 10 centimetres (3.9 in).
Provided adequate cover and structure is available this species is unfussy with regards to d?cor with ceramic flowerpots, lengths of plastic piping and other artificial materials all useful additions. A more natural-looking arrangement might consist of a soft, sandy substrate with wood roots and branches placed such a way that plenty of shady spots and caves are formed.
The addition of dried leaf litter (beech, oak or Ketapang almond leaves are all suitable) would further emphasise the natural feel and with it the growth of beneficial microbe colonies as decomposition occurs. These can provide a valuable secondary food source for fry, whilst the tannins and other chemicals released by the decaying leaves will aid in the simulation of a blackwater environment. Leaves can be left in the tank to break down fully or removed and replaced every few weeks. A net bag filled with aquarium-safe peat can also be added to the filter or suspended over the edge of the tank with the same purpose in mind.
This species seems to do best under fairly dim lighting. Although few plant species in the trade are native to Brazil, species from genera such as Microsorum, Taxiphyllum, Cryptocoryne and Anubias are suitable. A few patches of floating vegetation to diffuse the light even further may also prove effective. Filtration need not be excessive with an air-powered sponge or internal power filter set to a low flow setting sufficient.
