Hello Romain,
I keep my Paros in 25l or 45l aquariums. I use 100% RO-water and peat to lower pH. Water conditions are pH 4,3 to 6 (depends on aquarium) and conductivity 20 to 40 microsiemens. To filter the aquariums I use bubble filter with air pump. Substrate is sand or gravel, or lava gravel covered with leaves. I use coconut caves and caves for cichlids and caves for catfish. The aquariums are planted with Javafern, Javamoss, Anubias, Mayaca fluviatilis, small Echinodorus. Good structured aquariums (wood, stones, plants) are important! The surface is covered with Salvinia. Swimming plants are very imortant, because the larvae hide under the surface. Temperature is about 23 to 24°C. Paros are breeding continously but most larvae are eaten by older offspring…
I feed my Paros once a day with artemia and white or black mosquito larvae. They do not like Daphnia.
