Golden Wonder Panchax - Aplocheilus lineatus : Complete Fish Profile & Care Guide

Table of contents


The Golden Wonder Panchax is quite pretty and robust and is also relatively peaceful, very hardy and suitable for most community aquariums. These Killis are also quite simple to breed, making them ideal for both beginner and experienced aquarists. The Golden Wonder Panchax will usually leave other species alone so you can keep them alongside many other medium to large-sized moderately peaceful varieties of freshwater or brackish water species. Tankmates could include larger Barbs and Rainbowfish, peaceable Cichlids, Corydoras and Plecos. However, the Golden Panchax has a huge mouth, can be quite predatory and will relentlessly hunt and eat small fish. Therefore, it would be best if you did not house them with smaller species like Neon Tetras, Micro Rasboras, Pseudamugil Rainbowfish and Danios. Golden Wonder Panchax will quarrel amongst themselves, so it would be best if you kept these fish either singularly or in a group of at least six individuals, preferably more, making sure you have many more females than males. Golden Wonder Panchax will thrive in an aquarium with slightly soft water, a neutral ph, and plenty of hiding places. Driftwood, aquatic plants and floating plants will help achieve this. These fish will also need plenty of room to swim around. These fish will look much better in an aquarium with a dark substrate and plenty of light. A more spacious aquarium is recommended if you keep a larger group of males and females. You will need to provide good filtration and perform regular water changes to keep your fish at their best. The Golden Wonder Killifish is a very accomplished jumper, so your aquarium must have a tight-fitting lid. The Golden Wonder Killifish has an elongated slender body with a slightly arched back, and their dorsal fin is positioned towards the back half of their body. In addition, these fish have flattened heads, a pointy snout and an upturned mouth with no barbels. These fish also have a coppery bronze body with metallic yellow-gold scales along their sides that continue through their fins. The back half of their bodies have darkish vertical bars that end at the base of the caudal fin.

Natural habitat

The Golden Wonder Panchax is a gold variant of the Striped Panchax. This strain was created in captivity; therefore has no natural habitat. However, the Indian Striped Panchax is endemic to Sri Lanka and Widely distributed in Peninsular India in south Asia. The Golden Wonder Panchax inhabits slow-moving fresh and brackish waters, usually at high altitudes in swamps, paddy fields, streams and rivers, where they are used for mosquito control. Their habitats are typically covered in lush aquatic vegetation.

How to breed the Golden Wonder Panchax

A spawning pair of Golden Wonder Panchax can lay anything from 50 to 300 eggs daily, and spawning may continue for several weeks. These fish lay their eggs in fine-leaved plants or spawning mops. You should remove the plants or mops daily and replace them with new ones. Next, you should place the spawning mediums into a separate tank or container containing clean water with the same water parameters as the adult tank. The eggs usually take between 12 and 14 days to hatch. Once all the eggs have hatched, you will notice the fry has an apparent egg sac on their bellies; once the fry has absorbed the egg sac, you should then provide them with baby brine shrimp, microworms or powdered dry foods. You will notice that some fry may develop quicker than others, so there is the possibility of cannibalism. If you would like to raise as many babies as possible successfully, you will have to sort them by size to avoid this from happening. You will also need to pay close attention when feeding your fry, as uneaten food can quickly degrade the water.

Diet & feeding

The Golden Wonder Panchax is primarily a carnivore. They will feed on small aquatic insects, insect larvae, river worms and small crustaceans in the wild. In the home aquarium, these fish are unfussy and readily accept good quality dried foods such as flakes, pellets, and freeze-dried foods. However, to keep your fish looking their best, providing them with fair amounts of live and frozen food such as brine shrimp, bloodworm, mosquito larvae, and daphnia would be better.
