1. The age of the fish is not enough: the kissing fish does not have the habit of kissing when they are born. Studies have shown that it takes about two months of growth for them to start kissing.
2. The breeding density is too low: If the breeding density is too low, several fish are raised in a large fish tank, and they will grow in different places of the fish tank. They are less likely to meet, less likely to fight over territory, and less likely to kiss.
3, just change the environment: kissing fish need to adapt to the environment before there may be kissing behavior. If the fish are put into a new environment, they need to adapt to the environment first, and there will be no kissing behavior for a while.
4. Poor physical condition: If the breeding environment is poor, the water temperature is too low, or there is too little food, their bodies will gradually weaken and their vitality will decrease. If they are in an inappropriate environment for a long time, they are less likely to have kissing behavior.
Kissing fish do not kiss to "show love". Their kissing behavior is essentially a fighting behavior. They have serrated lips and hurt each other when they kiss. They have a gentle temperament and generally do not attack other fish. But they also fight to protect their territory when it is invaded. Therefore, kissing fish usually kiss when they compete for growth space.
