What is the reason why the puffer fish doesn't move under the water? Is it a sea fish or a freshwater fish?

Answer 1, abnormal pathological state: the puffer fish has decreased its physiological function due to various diseases, and then lies sideways at the bottom of the water. 2, stress reaction: new into the tank or new water change will produce a certain pressure, when the fish does not adapt, it will show the phenomenon of sinking, generally after a period of time to adapt. 3. Water temperature reason: If the water temperature is uncomfortable, it may sink to the bottom. 4. Water quality problem: Some puffer fish species have certain salt concentration requirements for water quality, and may sink to the bottom if they fail to meet the requirements. 5, normal physiological state: the puffer fish may be sleeping, so sinking at the bottom of the tank and moving slowly is a normal physiological state.

1. What is the reason why the puffer fish sank to the bottom of the water?

There are many reasons why puffer fish sink to the bottom, and the common ones are as follows:

1, abnormal pathological state

The puffer fish sinks to the bottom, which may be the decline of physiological function caused by various diseases, such as puffer fish outbreak, puffer fish hemorrhagic disease, trichinosis, etc., which may cause puffer fish to lie on the bottom of the water, and should be treated according to specific reasons.

2. Stress response

When the puffer fish is newly put into the tank or changed in water, it will produce certain pressure, and when the fish is not suitable, it will sink to the bottom of the tank and move slowly. This kind of situation usually gets used to it after a while. Don't scare the puffer fish before it adapts, so as not to leave sequelae.

3, water temperature reasons

The puffer fish has certain requirements for water temperature. For example, the water temperature required for zebra puffer fish is 25-28℃. If it sinks to the bottom, it may be caused by improper water temperature.

4. Water quality problems

The puffer fish has certain requirements for water quality. For example, the culture water of puffer fish (submarine) needs a certain salt concentration, and sea salt can usually be added to improve the sinking phenomenon. Can be added to water. Pay attention to sea salt, other salts containing iodine or other elements can cause fish poisoning and other problems.

5. Normal physiological state

The puffer fish may be sleeping, so it is normal to sink to the bottom of the tank and move slowly.

2. Is the puffer fish a sea fish or a freshwater fish?

1, most species of puffer fish belong to marine fish, and a few species of puffer fish belong to freshwater fish, including most puffer fish in salt water, which also spawn in fresh water during the breeding season. So whether it is a freshwater fish or a marine fish depends on which subspecies it belongs to, and it cannot be generalized.

2. puffer fish generally refers to fishes of various genera, such as teleost, bream and bream, because they are similar in appearance? Dolphin , and often in the estuary area, so Jiangsu and Zhejiang areas commonly known as puffer fish, is an important fish resource in China, mainly living in the middle or bottom of the water.
