About Bronze Corydoras

 

Bronze corydoras or bronze cories are small, tropical catfishes, which are one of the most popular aquariums fishes. These corydoras are usually found in South America, especially in Argentina and other southern areas.

Bronze cory is usually an inhabitant of slow-moving rivers and streams. Thus, they prefer a bit of shallow and muddy water.

But these fishes are so versatile that they can be easily found in fast-flowing rivers, stagnant ponds, and marshes. Nevertheless, only very few of them can survive in stagnant water.

They are pretty popular with their ability to breathe from the surface area of the water. Also, in your aquarium, you can see these catfishes darting near the surface area of the tank water for inhaling quick air, and once done, they will again dive back to the bottom.

Bronze corydoras are relatively small in size as aquarium fishes. Usually, the females are slightly larger than the male cory. Most females will grow up to 2.7-inches or 7 cm, while the males are 6.5 cm or 2.5-inches in length.

 

Bronze Corydoras Temperament

 

Usually, bronze corydoras are very peaceful and calm. These fishes are not at all aggressive and better kept with any friendly fish species.

Bronze corydoras are usually schooling fishes. So, it is better to keep them in a group of five. Due to their friendly and peaceful nature, they are an excellent option for beginners.

But these corydoras should not be kept with any aggressive fish like Oscars and cichlids as they can easily hurt your cute little cories.

 

Bronze Corydoras Tank Requirement

 

This species of corydoras is relatively easy to care for. Since these catfishes are too small in size, they do not need a much larger tank. You can easily start with a small 10-gallon tank for petting the fishes.

However, while picking a tank for your corydoras, make sure it is wide enough compared to its height.

Also, while choosing a filter for your bronze corydoras, it is crucial to remember that their filtration rate requirement is low. Also, the current in the water needs to be minimum. So, you can also use a hang-on-the-back filter for your fish tank. But make sure the tank is not over-filtered.

The substrate of the tank needs to be a suitable one for your corydoras so that they can stay happily. Do not offer these fishes a hard or sharp substrate that can hurt these tiny fishes.

These fishes are so tiny that, exclusively for them, the tank water’s pH level must be at a minimum. Also, the water temperature needs to be moderate to ensure proper care of the bronze corydoras.

 

Bronze Corydoras Tank Set-Up

 

Now, the tank set up for bronze corydoras is quite easy. But it needs to be very effective to offer the proper amount of care to these little aqua creatures. So, here is how the tank set-up must look like.

  • Though you can start caring for bronze corydoras in a 10-gallon tank, it is recommended to use a 20-gallon tank to offer them adequate space for hovering around.
  • Add a filtration unit with a minimal water current setting. A hang-on-the-back filter will be quite suitable for these tiny fishes.
  • Maintain the water temperature within 72-84℉ or 22-29℃.
  • Ensure that the tank water has a medium to normal pH level, i.e., between 5.5-7.5.
  • You may pick a sand substrate for your tank. Also, you can consider high-quality gravel coated with epoxy.
  • Add wood or rock formations in the tank, along with living plants, to offer your corydoras proper places for hiding and playing.
  • These tiny fishes prefer subdued lighting. Thus, floating plants will be the best for them.
  • Lastly, ensure 25% of water is changed every week.

Bronze Corydoras Tank Mates

 

Well, bronze corydoras come with a calm and non-aggressive temperament. So, finding tank mates for these corydoras will undoubtedly be an easy job for you.

Usually, the bronze cory is a schooling fish. Thus, it is recommended to keep them in a group of five members.

However, in the tank of bronze corydoras, you can easily include community tank species, as the cories are pretty friendly. But make sure you are placing your tiny cory with other small, peaceful, and friendly fishes. Never keep them with highly territorial large fishes.

So, here are a few suitable tank mates for bronze corydoras:

  • Otocinclus catfish
  • Tetras
  • Swordtails
  • Other cories

 

What Do Bronze Corydoras Eat?

 

If you want your corydoras to grow well, then offering them a proper diet is of utmost importance. But when you offer food to your cories and other fishes, mostly the latter will eat up all the food too quickly, leaving behind nothing for your corydoras. So, what to do in such a situation?

Well, change the feeding schedule of your cories. The best time to feed them is in the nighttime when the light goes off. Cories tend to become more enlivening in these hours. Thus, while feeding, make sure that your cories are getting a sufficient amount of food. But are you wondering, what do corydoras eat?

As bronze corydoras are usually omnivorous, you can easily feed them with any food. It is better to offer these tiny catfishes good quality sinking pellets for their staple diet.

Besides, algae wafers are equally good and healthy for these tiny fishes. Cories also eat spirulina flakes occasionally for a change in their diet.

For a protein-rich diet, you can offer them blood worms, brine shrimps, or daphnia twice a week. However, make sure you are not overfeeding your corydoras as they are very prone to digestive problems.

 

Care for Bronze Corydoras

 

Bronze Cories usually prefer a calm water flow. But they are easy to adapt to and survive in a wide variety of water conditions.

Usually, bronze corydoras prefer a bit acidic or neutral tank water pH. But make sure it is not alkaline, as such water condition can pose a high risk to your fish’s health. Slightly hard water will be best for their care.

So, are you thinking of adding salt to the tank water? Wait! Do not ever do that. Bronze corydoras are not at all tolerant of salt. If your community tank requires the addition of salt for the well-being of other fishes, make sure to move the cories to a separate tank.

Cories love to dig into the substrate in search of food. So, offer a comfortable and soft substrate to protect their barbels.

Besides, these tiny fishes are shy enough. So, make sure you are providing them with enough places to hide in the aquarium. Hence, wood and stones are mostly recommended. To keep them happy and maintain their proper growth, it is essential to let them feel safe.

Cories usually prefer a shallow, low water level. Thus, pick a wider tank with a low water level to offer them better space to play and live.

 

Bronze Corydoras Breeding Guidelines

 

Do you know bronze corydoras are one of the simplest ones to breed? So, if you want to get them bred, make sure to get at least one breeding pair.

During the breeding season, the females will be slightly larger. When they have a stockier kind of body shape, they will start developing eggs. During this time, the fishes get a bit mature and are easily fed with live and frozen foods while spawning.

Ensure that the water is slightly acidic during this time. You can also add some java moss, which will serve to be their spawning site. During this period, make sure the filtration is very light. An air-driven sponge filter is going to be ideal.

During spawning, the males will start chasing the female. But at this time, the females will be looking for their chosen site. Then, the females will chase the males. And soon after that, the pair will come together in the T position, signifying mating.

 

How to Care for Bronze Corydoras Fry?

 

To offer proper care to your bronze cories from the very beginning, it is better to encourage the breeding process in a separate nursery tank.

As soon as the bronze corydoras complete their spawning, you need to remove the parent fish from the nursery tank. After that, the eggs will hatch within 4-5 days.

So, are you wondering, what do corydoras eat? Well, there is no need to offer food to the fries right after they are born. The fry will consume yolk sac for the initial 2-3 days before they become ready to eat external food.

After that, you need to offer them their first meal. You can feed the cory babies fry food or infusoria. After two weeks, the fries will become large enough to accept proper meals.

So, now you can offer them newly hatched tiny brine shrimps. Also, you can feed them micro worms to make them well-habituated to every diet form.

However, always remember to perform regular water changes to ensure that the water quality is high enough for bronze corydoras fries. Poor quality water can risk the lives of your baby corydoras.

 

Where to Buy Bronze Corydoras?

 

Being one of the most popular aquarium fishes, bronze corydoras are relatively easy to find in any aquarist shop. And they are readily available at a fair rate of price.

Moreover, you can also get it from the shop of any hobbyist near you as they have a more extensive collection of aquarium fishes. Besides, many online stores sell high-quality bronze corydoras, from where you can buy a group.

 

How Big Do Bronze Corydoras Get?

 

Bronze corydoras are usually not so big in size. Instead, they are pretty small as catfish. These fishes grow up to only 7.5 cm or 3-inches. And do you know what is the most interesting fact here?

Unlike the majority of species, female bronze cories are slightly larger than the male counterparts. The females usually reach up to 7.5 cm in length. But the males are only about 6.5 cm in length.

How Long Does Bronze Corydoras Live?

 

Well, bronze corydoras are not too short-lived, which makes them perfect for keeping in a tank.  These catfishes usually live up to 10 years.

Also, with proper care and diet, they can last up to more than 10 years, which will be simply great for your tank.
