Nowadays, more and more aquarists like Black Emperor. Aquarists often write to ask about the future pattern direction of the little Black Emperor they raise. The Black Emperor is a kind of stingray whose patterns change more complicatedly as it grows. It is difficult to judge the pattern expression after maturity from just a few pictures of the young fish. Sometimes the pattern expression of a small fish will be very thick when the frame is large, but it will be a thin frame. Furthermore, even if the same fetal fish matures, the pattern expression will be very different. The big difference is that I have posted and shared with you the growth and changes of the Black Emperor that I have raised and seen over the past few years. Some of the records are not complete. I hope it will be helpful to everyone
1.
The little Black Emperor is just about two months old and has the same parents. At this time, his body color is yellowish brown and there is nothing special about him.
Photographed using different techniques
At four months old, you can see that the pattern is much clearer
At eight months old, the body disk is 25.6 cm. At this time, you can see that the bottom of the frame is clear and the thick part is retained. White lines
Photographed from a different angle and method
About eighteen months, when it reaches the flowering and maturity stage, it begins to spurt out broken flowers, and as the black background appears, the lines become more intense. It's getting thinner and thinner
It's been more than three years, and the pattern has basically been finalized after maturity.
The same embryonic fish has been selectively uploaded with several photos showing its patterns during its semi-adult stage. The dark green color in the pictures is due to the relationship between lighting, camera and shooting techniques. The essential color of the fish should be light yellowish brown and milky white. This is what it looks like. The approximate growth and change process of the first-born Black Emperor
2. There is also a type of Black Emperor who was very ugly when he was young and had insect marks. His performance at the time was not promising, but his subsequent changes brought many surprises.
When the previous one first arrived home, it had a very small circle and I was very disappointed with it.
A few months later
It was over a year old, and I saw that there was something promising about it. changes.
At this time, its potential began to be realized, and it became covered with insect patterns
Now, it is almost four years old, and the insect patterns have basically been finalized
This Black Emperor was previously kept in a dark tank with a red dragon, and was illuminated by TFC red tubes during its basic growth period
3. At first, I chose a Black Emperor with more figure-eight patterns and a more symmetrical pattern. The pattern symmetry of this Black Emperor is the best I have ever seen, but it is basically indistinguishable after maturity
As can be seen in the picture, the pattern is very symmetrical, and it was very difficult to find this individual at first< /p>
The changes after about half a year, shot with two white tubes and one basket tube lighting
The performance after giving birth to a child, shot with natural light
Almost four years old, the pattern has already Styling, ultra-white tube lighting shooting
The pattern of each type of black emperor has different changes as it grows, and there are individuals worth watching. The pattern changes of mature black emperors are less obvious, but as time passes, the pattern changes are less obvious. As the fish gets older, it will continue to spray out broken flowers to fill up the empty background. Generally, the pattern expression of each Black Emperor's offspring will continue the characteristics of the parent fish, but not every offspring is as beautiful as the parents, there will always be Individuals with unsatisfactory performance appear
