Ideal Tank ConditionsThe tank should have a sandy substrate. They can have rocks but this is not mandatory. The tank should have a lot of plants. A hornwort is an option. 25 % of the water should be changed every week. The nitrate level should be kept zero. A filtrate and heater are enough for an ideal tank.

The male courts the female and wraps around the female. The laying of eggs takes a few hours. The fry hatches in 30-90 hours. The male should be removed once the eggs are laid.
