Aquarium decoration

You may keep this species in a biotope or general tank. Biotop aquarium should have sandy substrate, floating pieces of wood, dried leaves of beech or oak which you need to change every few weeks, roots, dimmed light. Plants aren’t necessary. General tank should have a lot of plants, floating plants, dimmed light, places to hide among roots, place to swim, an effective but gentle filtration system. The fish are sensitive to water conditions. The aquarium should be systematically cleaned - partial water changes and the clean the substrate should be done every two weeks.

Breeding

This is an oviparous species. Breeding should be done in a separate tank – its capacity should be at least 30 litres. Tank should be covered and lights should be turned off because the eggs and young fry are sensitive to light. Aquarium should have soft water, pH=6-7, 24-26°C temperature, sponge filter with peat, soft and fine-leaved plants or a fish hatchery. Before spawning you should separate males from females and feed them with plenty of live food. The thickest female and the most colourful male should be transferred to the breeding tank, in the evening. They should spawn next day, in the morning. The fish will spawn every few days but male capability to fertilize the eggs will be gradually decreasing. You have to immediately remove the parents after laying the roe because they eat the eggs. The eggs hatch after 1-1,5 days. The fry starts to swim and feed 3-4 days later. Thereafter you should do partial water changes of around 1/3 of water every day.
