Neon iris: content and reproduction in an aquarium

Even if you are not interested in iris from Australian water bodies, neon iris is worth the time to devote a separate large article for her to study the aquarium dweller. It was brought to us from Germany and was called the diamond rainbow fish.

Neon iris is a real gift for domestic aquarists, as it has a number of advantages that should be discussed separately. But let’s not hurry, and we will consider everything in order. Immediately I would like to say about the coloring of the fish, which has much in common with the red neon from Amazon.

They even have the same color – blue and red tones.

The shape of the body in a neon iris is as in ordinary melanotenia: a cone-shaped body with a small, flattened head, large eyes. The body is tall with a special keel on the chest and a hump on the back. The anal and dorsal fins are long and girdle the back of the body.

The body is flattened laterally, this is especially noticeable in males, since the abdomen is rounded in females.

The color of the iris is specific and unusual. On the body there are no spots and stripes.

If the side lighting gets on the side of the fish, the scales glow with a bright blue tint. The reflective effect is enhanced by the fact that large scales have a dark edging.

It is necessary to change the viewing angle and the “lights” will begin to shine differently. But the fins do not change their color: in males they are red, and in females – with a yellow tint.

In general, such a color in fish is constant, regardless of the state of aquatic organisms, spawning period and mood.

With the onset of dawn in the fish mating games begin. Despite the fact that the fish are in an excited state at this moment, they do not harm their relatives.

That is, you will not notice flying flakes, strikes in the sides and other unpleasant moments that occur in the case of spawning in fish. The male will always be near the female and shows his nape of a light cream color, which indicates that the male is ready for spawning.

Spawning can be carried out in any small fibrous substrate, such as a ball of fishing line or a bundle of Javanese or Christmas moss. If there is a substrate in the aquarium, then all the eggs will stick to it, if it is absent, spawning can occur on a bare bottom, and the eggs will spread by the flow of water throughout the aquarium.

During spawning, the producers tightly press their sides against each other and tremble, and then spread out in different directions and the female produces a portion of caviar. There are cases when, during mating moments, a pair of males hang around the female, which clamp the female from both sides.

If there are no females in the flock of ready-to-breed females, or the ripened roe will be consumed, the males will calm down and the spawning rut will go to “no.” In the evening, it can happen again, but it is short-lived and without any consequences.

Parameters for spawning:

  • Water hardness 12 – 15 degrees;
  • Active reaction 7.0 – 7.2 pH;
  • The water temperature is 26 – 28 degrees.

The larvae of the neon iris are very small. The main food for larvae of the iris is located on the surface of the water, therefore, it is not necessary to fill the spawner with small live food.

Alternatively, you can grind various dry foods into dust and add vitamins and oil solution to them. The only problem with this feed is the fact that dry food absorbs moisture very quickly and sinks to the bottom of the aquarium. Just the fry of iridescents the first month of life from the bottom of the aquarium do not pick anything.

Accordingly, if you want the water in the spawning pool to not deteriorate, a filter must be present in the aquarium in a mandatory manner, and antsistrus must run at the bottom. In addition, a daily primer siphon will be required to remove excess feed from the bottom of the aquarium.

I would like to note the high voracity of the neon iris. During feeding, you may feel that these fish are hungry all the time and never eat.

It is enough for an aquarist to go to the aquarium to inspect it, as the whole school of fish gathers near the front wall. And if you throw food in the aquarium, the water in that place literally boils. There have been cases when some aquarists fed iris to iris only with dry food, but subsequently, such a regime could adversely affect the reproductive abilities of fish.

From the practice of breeding the iris can be concluded that the bloodworm is very bad, even if it is small.

For adults, there are no restrictions on nutrition. In a practical way, it was found that the neon iris gladly eats the planarium.

How to get rid of the planarians can read here.

The principle of reproduction of a neon iris is simple as 2 × 2. We take a flock of fish in the amount of 10 to 12 fish and plant them to spawn in a 40-liter aquarium without a substrate.

The chemical composition of aquarium water does not play a special role, and the temperature range has a rather large spread: 21 – 30 degrees.

Although in the case of spawning in cold water, all processes slow down significantly. A week after spawning, the clutch should be transferred to another aquarium, where it will be convenient for you to look after offspring.

And manufacturers put in a tank a bunch of moss or ordinary washcloth. This process can be repeated as long as you have a place for fry. The main difficulty in breeding neon iris is the constant need for small starter feed.

Older fry do not touch newborns, although their size is commensurate with food.

Fish reach sexual maturity at the age of 4–5 months, although the maximum size of the fish is not yet reached by this age. If you got up in the morning and saw a whitened neck of the males, then spawning began.

Neon iris is ideal for keeping in the general aquarium together with peaceful aquarium fish. Melanos is famous for its peaceful disposition, high activity and playfulness.
