Minnows, Shiners, And Chubs: What’s The Difference?


Although all these terms are interchangeably used while talking about or mentioning different species. But here are some of the factors that will make you understand how they differ from each other.

The first thing you need to know about them is that shiners spawn at a comparatively low rate compared with fathead minnows. Secondly, shiners have a larger size as compared to the minnows. This is what makes them slightly different from each other.

When it comes to the raising of these fish, minnows are raised at farms. While shiners are not grown in farms, instead they are found in the wild.

If we specifically talk about shiners, they are abundantly found as compared to tiger species. And they are found most commonly in freshwater resources like streams, rivers, etc. They are of an approximate length of 10 to 13 cm.

The thing that makes shiners different from other similar species is the presence of nine rays on its body. These rays are found at its mouth as well as anal fin. This is what makes you able to distinguish them from other fish.

If we consider the color factor, they have a lovely color pattern. The color of their back is greenish-blue. In contrast, their sides have a bluish silver color shade.

Like other species, males in this species also have a color change. Males of this species develop a red color on their tales and get anal fin. The appearance of this red color is an indicator that they are in the breeding stage.

While chubs can be differentiated based on their body color, generally, their back is colored greyish green. And their lower parts are white.


Where Do They Spawn & What’s The Life Cycle?


Minnows spawn very often. The places where they are more likely to spawn include ponds and freshwater lakes. And specifically, they place their eggs under the rocks, plants, and other things that provide them safe places.

The optimum temperature for the spawning of minnows ranges between 10 and 21 degrees Celsius. So, they spawn during the months of a year, providing them with the appropriate temperature. The most commonly spawn anytime between May and September.

If we talk about the life cycle of these fish, they start spawning by finding out the correct place for this process. For this purpose, the male fish start searching for the appropriate place.

And they find that place which is most commonly under the space of a rock or plant in the water.

Once they have found the needed place, they make that place more suitable and appropriate with the help of their mouth, and their respective organs are known as tubercles. After that, they start protecting that place against intruders and potential threats.

At this stage, the spawning place or nest is ready for laying of eggs. So, the male starts producing gestures and signals that attract the attention of passing females. These gestures may include random motions.

For example, whenever a female carrying egg passes by the nest, the male starts vibrating and tries to build close contact with that female.

It is also worth mentioning the fact that the males accept only the females carrying eggs. At the same time, the females without eggs are not allowed to enter or come near the nest. And then, it is time for the release of eggs.

When the male selects a female carrying an egg, he makes contact with her. Then the male pushes the body of the female against any rocky surface of the nest. This movement makes her body release eggs into the nest.

When the female’s body is releasing eggs, a stimulation causes the release of sperm from the body of a male. Then, after the successful fertilization of eggs, they are placed at a safe place in the nest. And this safe place is generally the ceiling of the nest.

After the implantation of fertilized eggs, the female is pushed away by the male. More than one female can also be allowed to lay eggs in the nest at the same time. The female who laid the eggs in the nest may come to the next provider if she still has eggs.

Male Minnow fish do their best to take good care of the fertilized eggs. They keep these eggs ventilated. They provide proper oxygen to them by fanning them. Moreover, they remove all unfertilized eggs and others to keep the nest neat and clean.

As mentioned earlier, the males also protect the eggs against predators and any threat they are exposed to—the eggs hatch after a time span of almost seven days.

And the newborn baby fish stay in the nest for a few more days until they become capable of moving and getting food for themselves.

Minnows Diet & Food


When it comes to the feeding of minnows, there are two ways they get food. One of them is natural feeding, and the other one is feeding in captivity. Here is all you need to know in this regard.

Natural Feeding

As we know that Minnow fish belong to an extensive family. So, there are different ways each member of this species adopts to gain food. Some of them rely on insects, water plants, insect larvae, and small animals.

Overfeeding

Overfeeding is one of the leading causes of death in fish. So, the quantity of food must be compatible with their eating capacity. Therefore, instead of putting their daily diet all in once, it is always better two split it into two times.
