Spike Tailed Paradise Fish (Pseudosphromenus dayi)

Brown Spike-tailed Paradise Fish are small, hardy, peaceful and timid fish that are pretty hard to get a hold of. However, they are not really suitable for the general community aquarium due to their small size and shy nature. However, you can maintain these fish in pairs or a group of 6or more individuals, providing you have more females than males. If you choose to keep this species in a group, you will notice some exciting behaviours.

Ideally, it would be best to keep these fish in a species only aquarium or an aquarium with other similarly sized species that share the same temperament. Ideal tank mates for these fish could include non-aggressive Cyprinids, Tetras, smaller Loaches and Corydoras Catfish. It would be best to avoid much larger boisterous species or species that are very similar in shape.

You can keep the Brown Spike-tailed Paradise Fish in a fully-decorated aquarium; however, many breeders prefer not to use a substrate as the aquarium is easier to maintain. Instead, it would be beneficial to add driftwood roots and branches to the aquarium to provide a few shady areas for your fish. You should also add a few cave-like areas using flower pots or coconut shells, so these fish have somewhere to lay their eggs.

The addition of dried leaf litter further accentuates the natural feel offering additional cover as well as giving microbe colonies a place to develop, providing a valuable food source for babies. These fish prefer reasonably dim lighting, so adding floating plants can also be helpful.

It would be best to have gentle filtration in the aquarium as these fish naturally inhabit still to slow-moving waters; therefore, a small air-powered sponge filter will be just fine. You should also perform regular water changes.

The Brown Spike-tailed Paradise Fish has an elongated brownish body that displays two dark, irregular stripes along the sides of the fish when stressed. The anal, dorsal and caudal fins are brownish-red with an iridescent light blue edge. In addition, the ventral fins are red with iridescent blue tips.

Natural Habitat

Brown Spike-tailed Paradise Fish are endemic to the coastal drainages of the Western Ghats mountains in southern Kerala state. You will find these fish in the Muvattupuzha, Periyar and Chalakkudy rivers in India. These fish inhabit sluggish to still waters in rice paddies, swamps, lakes, ditches, weedy ponds, and most commonly in floodplains and other lowland areas. Their habitats usually have thick growths of submerged vegetation.

What to feed the Spike Tailed Paradise Fish

Brown Spike-tailed Paradise Fish are somewhat fussy when it comes to their food. These fish will feed on zooplankton and insect larvae in the wild, so they should be offered small frozen and live foods such as grindal worm, white worm, artemia, and daphnia in captivity.

Dried foods may be questioned and even nibbled at but are not consumed sufficiently to achieve optimal conditions. Small insects such as fruit flies and crickets are also suitable; however, you must make sure you fill the stomachs of these by feeding them dried flakes or vegetable matter before offering them to your fish.

How to sex the Spike Tailed Paradise Fish

It is relatively simple to differentiate between male and female Brown Spike-tailed Paradise Fish. Males are more colourful and larger than females, they have orange colouration around their throat area, and their anal, dorsal and caudal fins are extended. In contrast, females are typically duller and smaller, and their fins are shorter.

How to breed the Spike Tailed Paradise Fish

Brown Spike-tailed Paradise Fish are bubble nesters. The male constructs a nest from bubbles under cave-like decor or a leaf. The pair will then wrap around each other and fertilise the eggs, which the females will then drop to the substrate. The eggs are then collected by both the male and female and placed in the bubble nest.

Once they have collected all their eggs, the female will have nothing more to do with them, and the male becomes solely responsible for guarding and tending the eggs.

The eggs usually hatch between 24 to 48 hours, and the fry will be able to swim freely 2 to 3 days after that. Once the fry becomes free-swimming, other fish in the aquarium may consume them, including their parents; therefore, it would be best to separate them and raise them elsewhere. In addition, the fry will be able to accept microworm and baby brine shrimp.
