* Gerbils are typically social: They live in colonies in the wild and share resources. While they might have a pecking order, they generally don't get into aggressive fights over water.
* Plenty of water: If there's enough water, it's less likely they'll fight over it.
* Other factors are at play: The most likely reasons for fighting over a water bottle are:
* Limited access: If the water bottle is small or there's only one, that could cause competition.
* Dominance: One gerbil might be more dominant and assert control over the water.
* Stress: If the gerbils are stressed (due to a new environment, overcrowding, etc.), they might be more likely to fight.
* Health issues: If one gerbil isn't feeling well, it might be more possessive of the water bottle.
What to do:
1. Observe: Watch their behavior closely. Is it just a little squabbling or a serious fight?
2. Provide more water: Make sure there's enough water for both gerbils. You can add another water bottle or a shallow water dish.
3. Separate: If the fighting escalates or you notice signs of injury, separate them temporarily.
4. Consider a larger cage: If their cage is cramped, it might be contributing to the stress and aggression.
5. Consult a vet: If you're concerned about their health or the fighting is severe, consult a veterinarian who specializes in small animals.
Remember: Gerbils are sensitive creatures, and it's important to provide them with a safe and comfortable environment.
