Housing Bronze Corydoras
The Bronze Catfish is the most popular of all the aquarium catfish. It is well known among aquarium hobbyists due to their brilliant body shape and hardiness. They are well suited to tropical freshwater community aquariums and they are not at all aggressive. It requires at least 10 gallons aquarium but larger is recommended. They do not do well in fish tanks with high nitrate and ammonia levels which lead to the infection of the barbells. The barbels may also be affected by constant contact with a sharp substrate.
The tank should be decorated with driftwood, dense vegetation and few floating plants with a dark substrate and an open space for swimming that provide relief from the light. The tank should have smooth sand or gravel substrates which do not damage barbells. Like other Corys they prefer the company of their own kind and should be kept in schools of a half dozen or more. Ideal tank mates include Guppies, Mollies, Platies, Swordtails, TetrasBarbs, Danios,Discus, Angelfish, Rasboras, Gouramis, Rainbowfish, Plecos. The water should be well aerated and an efficient filter is also needed. Proper care should be taken and 25-50% of the tank water should be replaced at least once a month. If the tank is densely stocked 20-25% water should be replaced weekly or every other week.
Feeding bronze corydoras
Bronze coredoras is omnivorous fish which mainly feeds on worms, benthic crustaceans, insects and plant matter. They also eat any dead, dying or even injured fish. In captive condition, they accept most food which sinks to the bottom of the tank. It should be supplemented sinking algae pellets with flake food or other sinking foods like catfish pellets.
