Aplocheilus Tank Requirements & SetUp/Tank Guides


It is easy and straightforward to prepare the tank setup for your aplochelius or striped killifish. Since the small size of them, you can provide a small aquarium for a small group. But the good standard is that the 20-gallon tank capacity should be enough for them to flock in groups and play around from corner to corner.


If you have more funds in your budget, it does not hurt to purchase a larger aquarium.


The fish group will spend most of their time from the middle to the top area. But they will often dart around at the top of the tank. It is also possible for them to escape from your tank by flying. Prevent them from escaping by installing a tight lid at the top of your aquarium.




When it comes to their biowaste, you shouldn’t need to worry since they relatively have small amounts. But a good filtration system is needed to keep the environment healthy. Keep in mind that you might add more tankmates for them.

which increases biowaste as well.


Objects and decorations


Besides the high-quality filtration system, you will also want to add a lot of plants to make them thrive. Floating plants are the most ideal and affordable solution. These will add nice nutrients to your aquarium. It will also make the lighting dimmer, providing good nuances for the fish to explore.


The golden killifish buddies are carnivorous. So, you don’t need to worry when adding delicate plants to the decoration of your aquarium. They won’t eat it.

The other natural decorations that you can add are outcrops, rocks, woods, as well as caves.


The caves will be a game-changer if you also put other fish in the tank. The caves provide a sanctuary for some Parisians. But on most occasions, the caves are a friendly shelter for your aplochelius pets.


To make the fish brighter and more vibrant in colouration, you could add contrast to your substrate. The experts would like to recommend a darker substrate to amp the colours up. Also, you could keep adding the floating plants to make the lighting dimmer.



Aplocheilus Water conditions


There appears to be no match for the killifish, which looks to be a resilient species that can survive in a variety of water conditions. Changes in environmental conditions do not significantly affect your buddies. These fish are capable of surviving in a wide range of temperature conditions.


Killifishes are required to maintain the same level of cleanliness in their water as other fishes. The Mysteries of the Golden Age When the water temperature ranges between 720°F and 770°F, it’s normal for killifish to bloom.


It is also necessary to consider the hardness of the water, in addition to its temperature, while making this determination. It is preferable to use pH-neutral water with a hardness ranging from 5 to 20 dGH. These fish have a pH range of 6.0-7.5, which is considered neutral. They can to relate the pH levels between these ranges. However, sudden fluctuations might not be a problem for them. But in the long run, it won’t be recommended either.


When the pH value is greater than 8, they become restless. Because the majority of water in the United States is moderate in hardness and pH, you may not need to change the water’s hardness or pH.


In spite of the fact that killifish pets are more tolerant of fluctuating water conditions, they still require their native environment, which includes streams, marshes, and lakes, in order to reproduce successfully. The presence of these components allows both freshwater and brackish aquariums to flourish.


For killifish that are sourced from brackish waters, you can turn the aquarium brackish by adding around 5 tablespoons of salt to every 5 gallons of water in the tank. Water should be changed on a monthly basis and filtered through a high-quality filter to guarantee that it is always fresh and safe to drink.


Since these fish demand slow-moving water, I’ve already mentioned that your filter system should be set up in this manner. Create a buffer zone around the property by planting huge trees or rocky outcrops.


Furthermore, because Golden Wonder Killifish are particularly sensitive to water conditions, it is important not to rush them through the process of acclimation.



Aplocheilus Tankmates


Actually, the golden Aplochelius fishes are peaceful community fishes. But in the group, the males tend to be more aggressive, especially when they are fighting over the females.


There will be times when you see your killifish fighting each other for romantic purposes. But with the other tankmates, you can rest assured that they are peaceful towards other species.


They can co-habit with other non-aggressive catfish like Pleco, community fishes, and moderately peaceful species as well.


The fishes that are able to survive in freshwater can be good companions for them.

The other good tank mates are tetras, catfish, cichlids, and rams.


Aplocheilus Diets/Food/Feeding


The golden wonder killifish is carnivorous. They feed on meaty items like worms and insects, as well as crustaceans. But they can also feed on pellets, flakes, and even wafers that you’ve purchased from the nearby department store.


They will consume all animals that fit in their mouths. They are not picky eaters either.


Although carnivorous reigns in their blood, they can also eat dry plants. But you will want to mix the items with something that is rich in vitamins and other nutrients.


In difficult times, they can tolerate commercial foods and frozen foods. But you will need to add more live foods more often since it is the key to their bright colouration and quality of life.



Aplocheilus Breeding guidelines



This fish is easy to breed. You will need to separate the couple from the main tank. Set the water to soft and acidic with around 6.7 pH.


Do not add complicated decorations since you won’t need them. Employ a good ratio of male and female breeders. That requires one male and two females. Of course, you need to prepare a separate tank to make it work.


They will lay the eggs in the safest place. The hatching will take place in 10 or 14 days, depending on the quality of the water and fertilizer.
