However, many breeders are confused when it comes to distinguishing male and female pachyderma fish. This article will combine the hot topics and hot content on the Internet in the past 10 days to introduce you in detail to the method of distinguishing male and female thick line fish, and provide structured data to help you better understand and apply it.
1. Differences in appearance between male and female slugs
There are obvious differences in appearance between male and female fish, mainly in body size, color and fin shape. The following is the specific comparison data:
| feature | male fish | female fish |
|---|---|---|
| body shape | Slender and smooth lines | More rounded, slightly enlarged abdomen |
| color | Bright body color with obvious stripes | The body color is lighter and the stripes are softer |
| dorsal fin | The dorsal fin is long and pointed | Dorsal fin short and blunt |
| abdomen | Flat belly | The abdomen is slightly distended, especially during the breeding season |
2. Differences in behavior
In addition to the differences in appearance, there are also obvious differences in behavior between male and female linefish. The following is a comparison of the behavior of male and female fish:
| Behavior | male fish | female fish |
|---|---|---|
| swimming style | Swims quickly and likes to show off | Swims slower and quieter |
| territoriality | Very territorial and will drive other fish away | Weak territorial awareness and gentler |
| reproductive behavior | Actively chases female fish, showing off bright body colors | Passively accept the chase and find a suitable place to lay eggs. |
3. Special manifestations during the breeding period
During the breeding season, the performance of both male and female fish will be more obvious. The body color of the male fish will become more vivid, especially the color of the dorsal fin and tail fin will be more prominent. The abdomen of the female fish will be significantly enlarged, which is a sign that the eggs are mature. The following is a comparison of the characteristics of male and female fish during the breeding period:
| feature | male fish | female fish |
|---|---|---|
| Body color changes | The colors are more vivid and the stripes are more obvious | Little change in body color, enlarged abdomen |
| behavioral changes | Frequently chases female fish to show body color | Find a hiding place and prepare to lay eggs |

1.Judging by color only: Although the color of male fish is usually more vivid, some female fish will also show brighter body colors under certain conditions, so it cannot be judged by color alone.
2.ignore age factor: The gender characteristics of juvenile fish are not obvious, and they need to wait until sexual maturity to accurately distinguish them.
3.Overreliance on a single feature: Judgment should be made based on various characteristics such as body shape, color, fin shape and behavior.
6. Summary
To distinguish between male and female fish with thick-lined lines, we need to comprehensively observe the appearance characteristics and behavioral performance. Male fish are usually slender, bright in color, with long and sharp dorsal fins, and are more active in behavior; female fish have round body shape, lighter in color, shorter in color and blunt in dorsal fins, and are quieter in behavior. These characteristics are more obvious during the breeding period. Through the above methods, you can more accurately judge the gender of thick-lined fish and help raise and reproduce.
