Your fish might be playing with bubbles because they find them stimulating and enjoyable. Some fish species, like pufferfish, are known for their intelligence and playful nature, and they might see the bubbles as a form of entertainment.
Here are some other possible reasons your fish might be interacting with bubbles:
- Natural instinct: Fish naturally associate bubbles with oxygen and might be instinctively drawn to them.
- Stimulation: The movement of bubbles can provide visual and tactile stimulation for fish, particularly those in smaller tanks or with limited space.
- Boredom: In a monotonous environment, bubbles can provide some entertainment and break up the routine.
While playful interaction with bubbles is generally harmless, it's important to note that some fish might mistake bubbles for food. If you observe excessive bubble chasing or your fish seem agitated, it might be worth adjusting the bubble flow or removing the air stone temporarily.
