Pearl Tiger< /p>
Tanhu cichlids are a subcategory of the Three Lakes cichlids. They have many varieties. It is known that there are more than 200 species of Tanhu cichlids. They all come from the first 7 ancestors. The Lake Tan cichlid is considered to be the most unique among the three lake cichlids, because more than 95% of the cichlids cannot be found in any other places.
The evolution of cichlids has made them adapt to the special ecological conditions of Lake Tamagotika. In fact, many species can live together in a short section of sloping waters, which also proves that this section of water can provide fish with a sufficient number of effective ecological niches and sufficient food supply. In order to cope with the harsh living environment and rationally allocate limited natural resources, in the long-term natural evolution, the Tanhu cichlids have developed many evolutionary branches through a high degree of disintegration. Each population often takes what they need without interfering with each other, and this is how the evolutionary principles among Lake Tan Lake cichlid species are established. There are many varieties of sea bream. Here are three representative species of sea bream for your reference.
1. Pearl Tiger
Pearl tiger is a very special fish species. Its flat body is particularly suitable for moving in rock crevices. When attacked, it will avoid the enemy by circling. This ability also expresses During the current slit movement: rotate the horizontal target 90 degrees.
In the natural environment, the pearl tiger's foraging ability can be said to be unique, although they often look lazy Yangyang, but their movements when catching food are very fast. When they lock on the target, they will stop swimming, move their heads downward in a nearly vertical posture, and prepare to attack the prey. When growing up, female pearl tigers often look for a hole, rock crevice or even a shell that is suitable for shelter. The nest is generally not big enough for male fish to enter, and the female fish is just right enough to block the hole with her body to protect the eggs, but they Usually only the young fish are taken care of until they hatch. After the young fish hatch, there is only maintenance. The young fish will leave in a few days.Living on their own, the young fish look dim and swim only in small circles to avoid predators.
In the process of raising pearl tigers, you must first protect a large enough water body, because basically Firstly, pearl tigers will be raised in groups, and secondly, as many caves as possible will be built through rock landscaping for them to live. In terms of food, pearl tigers are carnivorous fish and move very fast. When they are alive, they will often steal the juvenile fish of other three lake cichlids for food, so special attention should be paid to this. Although pearl tigers are fed mainly ready-made feed and frozen adult shrimps, they can also be fed live foods such as adult shrimps and red worms on a regular basis, but it is not recommended to use these dried as their staple food.
Two, Blue Wave
Blue Wave
Blue wave belongs to the mouth-brooding growth type. This is also the most standard mouth-brooding method. Male fish in estrus often They gather to form a growing group. Each fish first builds a huge dune with fine sand on the surface of rocks or sand (the diameter can exceed 1 meter). The top is flat and slightly concave, and then leads the female to join. The yellow spot (false egg) at the end of the pelvic fin indicates the place where the eggs are laid. The female fish will lay eggs due to the opening of the false eggs and go back to pick up the eggs, because the male fish will first eliminate the semi-liquid semen at the place where the false eggs hang down. , so the female fish can be fertilized when the eggs are in the same place, that is, the eggs are fertilized before the female fish holds the eggs. After repeated several times, the female fish can hold up to about 25 eggs in her mouth. Female fish that hatch in the mouth often gather in groups. They live in shallow water and release young fish simultaneously after 3 weeks (the hatching period is about 2 weeks).
Three and six rooms
Six rooms
The six-room cichlid is the representative species of Lake Tamagoyike, and it is also the three-lake cichlid species that is popular among people. The Liujian fish is a deep-water fish that lives in rocky places. It is a rock-dwelling cichlid and is scattered in various areas of Tanhu Lake. They are called "six rooms" because they have six black lines on them. Liujian fish is a giant cichlid with a length of 33 to 38 centimeters. It is suitable for living in alkaline hard water and the temperature requirement is maintained between 22 and 28 degrees. The Liujian fish has a gentle nature, and its movements are slow and graceful when swimming, which has won the favor of many people. The rare Tanhu Liujian fish in the market mainly include Burundi Liujian, Sailan Liujian, Mambo Liujian, etc.
Speaking of Liujian, we have to mention that there is a famous regional variety - Sai Blue, whose color The performance can be said to be the ultimate of Liu Jian, but because it has a small output and a large number of similar strains, there have been many disputes over whether there are less blue Liu Jian, which is called Sai Blue, filling the shopping mall. However, leaving these issues aside, Liu Jian did not talk about it. It can be said that Liu Jian is a fish species with quite unique characteristics. Compared with ordinary Tan fish, Liu Jian's movements often have a more calm and elegant feeling. This may have something to do with his size and habitat, but when he is free, There is a lot of murderous intent hidden under the surface. The reason is that he is a piscivorous fish species, but because he is not a fast swimmer, he will not blindly chase fish. Instead, he will wait for other fish to seek shelter on rocks when night falls. When entering a slumber dream, or in the early morning when the fish has just woken up but is unconscious, it launches an attack from its hiding place. In the natural environment, the main prey is Cyprichromis (blue sword sand), and the old food is caught during the day. , childish Lan Jiansha.
