1、? Body shape: most tigers are generous, and their body length can reach about 60 cm in the aquarium. Most of them are "V" tails, only a few are slender, and most of them are "CT tails" and "H" tails. In fact, I think body shape can be used as one of the basis to distinguish between men and women. There are many ways to distinguish between men and women, such as gill cover, body color, anus and so on. Even if it is distinguished, it will not have much effect, and it is basically impossible to reproduce successfully in an aquarium.
2、? Body grain: Body grain has three lines and four lines, with three lines being the most common. The lines behind the buccal lid are mostly S-shaped, and the lines in the middle are sickle-shaped, pointing to the back of the anus. The three lines are basically straight, the middle line and the three lines are basically parallel, and most of them are wider than the three lines. There are three tails (Indonesia tail) and two half tails (V tail and CT tail). It is wrong for many new tiger breeders to use the tail line to distinguish between Indonesian and Thai tigers.
3、? Body color: Because tigers live in different regions, there are red-skinned tigers and yellow-skinned tigers. Most tigers are relatively stable and rarely turn black. Only when fighting with other fish, the color will become very dark and the lines will become equivalent to skin color.
4、? Fins and tail stalks: The fins and tail stalks of Thai tigers over 30 cm are dark in color and have many spots. The bigger the tiger is, the older the fins and tail handles are, and the more black spots there are.
Indonesian tiger fish:
1. Body shape: Most indonesia tiger are slender, and their body length can reach about 55cm in the aquarium.
2. Body lines: Body lines are divided into three lines in indonesia tiger and four lines in indonesia tiger. Most of the lines behind the buccal lid are "1", the middle line is "s", some are "1" or sickle, and the third line is "7".
The middle pattern and the three patterns are not parallel, and most of them are eight-shaped. It is very important that the middle grain of the three lines of the tail grain has a little connection with the last grain, which can be seen by careful observation. The picture below is also marked with a circle.
3. Body color: Most indonesia tiger's body color is black, yellow or black, black and yellow when in good condition and black when in bad condition. Of course, it has a lot to do with the background, environment and water quality. Indonesia tiger also has the saying of red skin and yellow skin, which is also related to the place of origin.
4. Fins and tail stalks: indonesia tiger's tail stalks and fins are basically free of spots. The bigger the spots, the less they are, and they are basically black and transparent.
