Day's Paradise Fish

Named for Francis Day, Day's Paradise Fish is also commonly known as the Brown Spike-Tailed Paradise Fish. This nickname is derived from the light brown coloration of this species' body in combination with the pointed dorsal and anal fins. These fins, along with the spade-shaped caudal fin, are often tipped in light blue. Day's Paradise Fish are endemic to the Kerala state in India where they inhabit bogs, ditches and small ponds.

Tank Set-up

Day's Paradise Fish are unparticular when it comes to water chemistry. They can survive in temperatures ranging from 60 to 90 degrees Fahrenheit but thrive in warmer temperatures. These fish prefer tanks that mimic their natural habitit - the tank should be densely planted to provide plenty of cover. Unlike some Paradise Fish, Day's Paradise Fish are fairly peaceful and can be kept in a community tank. Because their long fins are prone to nipping, however, they should not be kept with Tetras or other known fin-nippers like Tiger Barbs.


These fish are likely to accept any food offered but should be given a staple diet of high-quality dried flakes and pellets. In order to encourage healthy growth and coloration, this diet should be supplemented with small live and frozen foods such as bloodworms, Daphnia and Artemia.


Breeding Day's Paradise Fish is fairly easy. This bubble-nesting species may build its nest in caves rather than among floating vegetation but, in typical anabantoid fashion, spawning will still occur beneath the nest. Following spawning, the male of the species will transport the eggs to the nest and guard them. The eggs typically hatch after 24 to 36 hours and the fry will become free swimming after another 2 to 3 days.
