The guppy likes surfing at the outlet probably because it likes running water, which is very interesting. So, they will wander around the water outlet for fun.

In addition, guppies may surf at the outlet to clean themselves. In the process of surfing, the current can wash away some dirt or parasites on them and keep them clean and healthy.

It should be noted that guppies may be overtired and affect their health if they surf in outlets for a long time. Therefore, in the process of foraging, it is necessary to provide them with enough activity space and enough food to avoid their overwork due to foraging.
