These fish usually inhabit clear and moderately flowing streams and rivers, elevated up to 1000 feet from sea level. Besides, the Giant Danio Devario aequipinnatus are pretty tolerant in varying water conditions. They mostly prefer a shaded environment with smooth rock and gravel substrate and sometimes reside in dense vegetation.

Giant Danios are listed on the IUCN Red List as Least Concern because they are very common and available in a wide range of India.

These fish species come with a nice and pretty appearance. They have an elongated body with a torpedo-shaped structure. Also, these Danios possess a barbel at the end of every lip.

 

Besides, Giant Danios come in a variety of colors. Their base color comprises a pretty greyish hue, with a touch of yellow and green colors. And either side of their body has a bright bluish-green colored wide stripe. One can also find a variety of yellow stripes and blue spots all over their body.

Giant Danio Temperament

 

The Giant Danio fish is not at all aggressive. They are best kept in large schools of their own types.

These Danios typically come with a unique playing behavior. They either tend to harass the smaller fishes or sometimes mildly annoy the large fishes. However, they do not cause any harm to the fishes.

This behavior of Giant Danio Devario aequipinnatus is sometimes mistaken as aggression. However, they are not at all aggressive. Instead, they are naughtier than any other Danio species.

Giant Danio Tank Requirement

 

Giant Danios are much easier to care for in a proper tank set-up as they tend to adapt to a variety of aquarium conditions.

Usually, the Giant Danio Devario aequipinnatus fish hovers around in the top and middle areas of the tank. They have a high activity level in the tank. And this why it is important to make sure that you are adding enough free space in the tank.

While keeping Giant Danios in a freshwater tank, facilitate a proper filtration rate in the aquarium water. Make sure that the tank has an appropriate level of water current and enough oxygen for their living.

Giant Danios are much more comfortable in a stable water parameter with subdued lighting and a nicely decorated aquarium. They like to dwell in a well-planted tank, which helps them stay safe and renders a lesser amount of stress.

The water quality of the tank has to be top-notch for taking good care of your fishes. These pretty Danios require clean water with a strong current in it.

Also, the water temperature for their tank must be moderate enough. The water shall neither be too cold nor too hot. Also, maintain the water parameter within a range of slightly acidic to neutral conditions.

Also, make the addition of live plants to the fish tank. These Devario aequipinnatus species love to thrive in loads of vegetation. Hence, adding tall plants and other varieties would undoubtedly boost the oxygenation needs of your fish.

Giant Danio Tank Set-Up

 

To take good care of your Giant Danio Devario aequipinnatus, you need to facilitate them a correctly set aquarium. The tank must house a sufficient quantity of assortments that can keep them safe and protected against predators.

So, here is how you can ensure a proper set-up of the tank.

  • Giant Danios love to have ample space in the aquarium. Also, to keep them away from disturbing other fishes, it is better to pick a large freshwater tank. So, the minimum tank size should be 30 gallons. Also, pay close attention to the length of the aquarium rather than the depth.
  • Any substrate can be laid at the bottom of the tank. However, make sure the substrate is smooth and soft enough to prevent your Danio’s barbels from getting damaged.
  • These fish do not prefer too much bright lighting in their tank. So, it would be better to add moderate to normal lighting to the aquarium.
  • As the Giant Danio Devario aequipinnatus species originate from streams and rivers, they thrive best in neutral or slightly acidic water parameters. Thus, keep the pH level of the water around 6-8.
  • Maintain the water hardness range within 2-20 dGH.
  • Add strong water movement to the aquarium. Thus, incorporating a strong filtration unit will provide the required current and water flow to your Danios.
  • As the water temperature of the aquarium needs to be moderate, keep it between 72-82℉.

Giant Danio Tank Mates

 

Since Giant Danios are not much aggressive, they are great for petting in a community aquarium. But it is better to consider a larger tank to ensure that they are not coming in the way of other tankmates.

Besides, these Giant Danio Devario aequipinnatus serve to be poor tank mates for those fish species, which require a very slow pacing environment. These fishes are themselves very fast, and they can potentially annoy other slow-moving fishes. So, it is advised not to house them with slow swimmers.

Due to their moderate size, Giant Danios must not be kept with too small fishes that easily fit into their mouths. So, medium to large fishes with similar behavior and size would be better tank mates for your Danio.

Since Giant Danios are schooling fish, always try to keep them in a shoal of at least 8 specimens. Keeping Danios in small schools with only 5-6 fishes can make them quite aggressive towards their own species. Thus, always consider larger schools over the smaller ones.

Nevertheless, here are a few suitable tankmates that you can consider keeping with Giant Danios.

  • Medium to large size Characins
  • Cichlids
  • Cyprinids
  • Danios
  • Barbs
  • Loaches
  • Catfish

What Does Giant Danio Eat?

 

These fish species are omnivores by nature. Thus, feeding Giant Danios in your tank will not at all be a challenging task. Giant Danio Devario aequipinnatus readily accepts any suitable fish food products.

These fish eat both prepared or live aquarium fish foods. Since Giant Danios are highly active, they require a nutritious diet with a proper food supply to get enough fuel for their daily activity. Hence, it is crucial to provide them flake food products to serve them all the healthy nutrients necessary for their living.

In their wild habitat, the Giant Danio Devario aequipinnatus fish quickly picked insects and other invertebrates from the surface area of the water. So, they don’t usually chase after the food leftovers settled at the bottom region of the tank.

So, to offer them proper health with the right food item, you can add pellets or tablets to the diet of your Giant Danios. Also, these freshwater fish species love to feed on live foods like small fishes, brine shrimp, blood worms, daphnia, insect larvae, and mosquito larvae. To add variation in their diet, you can easily offer them fish foods like algae wafers, blanched vegetables, etc.

So, are you thinking, how frequently you should feed your Giant Danios? Well, it would be better to offer them several feedings a day. Giving one large feeding will not at all provide them proper nutrition. Give them only that much amount of food, which they can easily consume in minutes or less, every time you feed them.

Care for Giant Danio Devario Aequipinnatus

 

Giant Danio species require adequate care in their tank to have better growth. Thus, it is essential to make sure that you are giving them a suitable tank atmosphere with sufficient water parameters.

These Giant Danio Devario aequipinnatus are not much difficult to care for in a tank. But you need to ensure that you are performing regular water changes every month. It is recommended to do at least 25-50 % of water change in the aquarium.

If you have dense vegetation in the tank of your Giant Danio, then make sure you are performing the regular water change weekly. Also, maintain the optimum temperature and pH level of the tank water.

Over time, the decomposing organic matter can cause nitrates and phosphates to build up in the water, increasing the overall hardness. Thus, make sure the aquarium has a good filtration unit to facilitate clean and stable water quality.

Giant Danio Breeding guidelines

 

Breeding Giant Danios in your tank is not much difficult. You can easily breed them in your home tank to achieve a successful spawning.

Generally, Giant Danios become sexually mature when they reach up to a length of 2¾- inches. Like any other Danios, these fish species are also prominent egg scatterers. Hence, they do not require any specific breeding site for spawning.

Nevertheless, these fishes are better cared for in a separate tank during their breeding. You can keep the adult Danios in a 20-gallon breeding tank with thicker and dense vegetation. You can also make the addition of bushy plants or clusters of other plastic plants to facilitate them a lot of space for hiding and feeling safe.

The water in the tank of your Giant Danios needs to be very fresh and clear with an optimum temperature. You must also increase the water temperature slightly near 72-82℉. Also, make sure you are keeping the aquarium oxygenated enough by using an air pump.

Usually, to form a breeding pair, it is suggested to add two fish specimens. Incorporate the female Giant Danio in a separate tank one day before adding the male specimen.

It is also recommended to keep the aquarium at a place where direct sunlight can reach it. As the morning sunlight hits the tank, it triggers them to start mating.

If their spawning reaches a favorable condition, the female fish start releasing their egg in the open water. And then, the male Giant Danio fish species move towards the laid eggs to fertilize them.

The female specimens usually release at least 5-20 eggs after each of their pairings. These species keep pairing until the females lay almost 300 eggs. They scatter their adhesive eggs across the water column, making them fall towards the substrate area.

However, if the aquarium has dense vegetation, those eggs will adhere to the leaves of your aquarium plants or on other tank objects.

Besides, during the time of spawning, it is better to feed the parent Giant Danios live worms so that they stay away from eating the eggs.

Now, their eggs typically hatch in 1-2 days. And their offspring keeps hanging from the plants and glass for up to 3-5 days until their yolk sac gets absorbed. After that, the fry comes out to swim freely in the tank. And at this time, remove the parent fishes from the tank to prevent them from eating your small fries.

Soon after the fish fry becomes ready to accept outside foods, you can easily feed them powdered dry foods and small live foods like brine shrimp, mosquito larvae, etc.
