Macropodus opercularis

The paradise fish has been familiar to aquarists since the mid- 1800s. It is the "black sheep" of the family, but possesses the advantage of withstanding temperatures down to 15%C - sometimes even lower for short periods. The female lays several hundred eggs which hatch in 2 days or so. Size: 10-15 cm.
