Food habits of corydoras
In nature, corydoras live in relatively slow-moving areas such as river tributaries and the bottom of ponds, and eat organic matter and microorganisms that accumulate at the bottom. It uses the whiskers around its mouth to search for food, and then sucks in the food it finds.
The sight of them fluffing their food while eating is very cute, and it makes sense that there are enthusiasts who specialize in breeding corydoras. This time, I summarized the food for breeding corydoras in an article./
Corydoras Feeding Amount and Frequency
Basically, you just need to give them enough food so that they don't leave any leftovers, but the amount varies from individual to individual. Therefore, it is important to determine how much the individual you are raising will need.
amount of food
The amount should be adjusted according to the type of food you give. For example, a relatively large tablet type is designed to be eaten over time, and the amount of such food that can be eaten in a few hours is appropriate. For other corydoras, the amount of bite-sized artificial feed that can be eaten in about 3 to 5 minutes is considered appropriate.
The same is true for live food, the amount that can be eaten in about 3 minutes is appropriate. In any case, the basic rule is to give enough food so that there is no leftover food. For details, please follow the instructions on each package.
The number of times is also different depending on the product. About adult fish Three times a day at the most, and once a day is enough if you don't want to lose weight.In the case of fry obtained by breeding, it is better to give a small amount several times a day so that they do not leave food in order to get out of the period with a high mortality rate early.
Corydoras are voracious eaters as they are catfish mates, but the amount they can eat in a healthy way varies from individual to individual. Please observe and feed the animals you are raising so that they can eat the amount they need./
Best food for corydoras
Here are some recommended foods for corydoras. A well-balanced and varied diet is important for keeping corydoras healthy.
Tablet-type food has long been sold as food exclusively for Corydoras. Since it is difficult to dissolve in water, it is difficult to pollute the water, but on the other hand, if you are raising a small number, you need to be careful of leftovers.

Artificial feed for bottom-dwelling fish that often eat animal matter such as corydoras and roach. Because the vitamins required by Corydoras are strengthened, you can expect healthy growth.

It also contains Toyoselin, a live bacterium, which promotes the decomposition of feces and can be expected to have the effect of suppressing the deterioration of water quality.
Compared to tablet-type baits, many of them are smaller in size, and they have the feature that they can be fine-tuned even when breeding a small number of corydoras.

Live bait/frozen bait

Freeze-dried red bugs, the larvae of midges, are natural feed. Various vitamins are added to reinforce nutrients. Since it exhibits a palatability that cannot be reproduced with artificial feed, it is ideal for feeding and when you want to add nutrition.

Frozen products are mostly sterilized during processing, so there is no need to worry about pathogenic bacteria. It has a high palatability similar to bloodworms, and its bite is different from artificial feed.
3 Tips for Feeding Corydoras
Here are some tips for feeding corydoras. In addition to the amount and frequency of feeding mentioned above, please pay attention to the following precautions.
Feed very little at a time
Unless you know how much food your corydoras need, it's a good idea to feed them in small amounts at a time. I mean, Corydoras are more damaged by the deterioration of the breeding environment due to leftover food than by the lack of food.It's for
Leftover food stays on the substrate as garbage and contaminates the breeding water and substrate material. Please note that corydoras, which usually live in the bottom, are susceptible to adverse effects due to dirt on the bottom floor, and symptoms such as whiskers melting and disappearing may occur.
Make effective use of the dropper
When you want to feed corydoras live in a mixed tank, use a long dropper that reaches the bottom of the tank. Since live bait is highly palatable, it is not uncommon for it to be intercepted by tankmates and not reach the corydoras even if it is thrown in from the surface of the water.
So let's make good use of the dropper. If you put the thawed live bait into the breeding water, suck it with a dropper, and spit it out in front of the corydoras, you can feed it without being intercepted.
Give food in daylight
Corydoras are generally diurnal, so feed them when the sun is out. At night, corydoras are also sleeping and resting, and are less active. Feeding at such timing may cause indigestion and cause poor physical condition.
Corydoras also has a biological clock, A regular life is essential for healthy growth.Try to give food at a fixed time in a bright time zone as much as possible./
What to do when corydoras won't eat
When corydoras suddenly stop eating, it may be due to the deterioration of the breeding environment. It is necessary to check the water temperature, water quality and the condition of the substrate.
First, use a water thermometer to check if the water temperature is the right temperature. If temperature control devices such as heaters are out of order, depending on the season, the temperature will be outside the optimum temperature, and the activity of corydoras will decrease, resulting in poor feeding.
Next, check the water quality with a tester. When the water becomes dirty, the pH of the corydoras tends to become more acidic, which can lead to stress and loss of appetite in the corydoras. In addition to pH, it is also a good idea to check whether the concentration of toxic substances such as ammonia and nitrites is high.
Finally, make sure the substrate is clean. If the substrate is dirty, you will need to reset the aquarium to wash it. Resetting the aquarium is a task that will be necessary eventually, but it is a big job, so I want to reduce the number of times it is necessary.
In order to maintain it for a long time, it is recommended that you do not leave food leftovers during daily feeding, and use a bottom sand cleaner to clean the bottom floor when changing water.
For corydoras, the remaining food in the aquarium is not enough!
There are some cases where Corydoras is introduced as a cleaner organism, but the leftover food of tankmates is not enough nutrition. Corydoras is a relative of the catfish, and is a big eater for its size. If you don't feed your corydoras properly, you will not only prevent them from growing healthy, but in the worst cases, they will starve to death.
Also, pay attention to the type of food. In the natural environment, corydoras often eat animal products, so if you don't feed them food formulated for corydoras, they won't be able to get the nutrients they need, which can cause them to get sick.
in the first place, Feeding so much that there is leftover food is the wrong feeding method from the viewpoint of maintaining water quality.Basically, give it so that there is no leftover food, and prepare food for Corydoras for Corydoras.

Corydoras is a tropical fish that is often introduced as a cleaner organism, but it is important to properly feed it for healthy growth. Even in the sense of preventing water quality deterioration, please be careful not to leave any leftovers when feeding.
