not swim.

可能係因為你條魚大肚,受傷或者病左.當魚病左,就會好像人纇,無體力,就吾會swim.大肚都會係,無體力,所以吾游水.你留意下條魚有無特別,如果有就買本書see下啦~

Maybe because your fish is pregnant, hurt or sick.If fish were sick, it will don't swim because your fish did not have any energy.But if your fish were pregnant, it will don't swim too.Have no energy.Just buy some books about fish, read it then you will know why.

Maybe your fish too fat,if your fish is pregnant,it don't want
to swim.
