* Different Needs: Fat-tailed gerbils and other gerbil species have different dietary requirements, activity levels, and social structures.
* Potential for Aggression: While gerbils are generally social animals, introducing different species could lead to territorial disputes and aggression. Fat-tailed gerbils are known to be particularly territorial.
* Disease Transmission: Different gerbil species can carry different parasites and diseases that could be transmitted to each other.
It's always best to keep gerbils of the same species together. This ensures that they have compatible needs and reduces the risk of conflict and disease.
If you're considering getting multiple gerbils, research the specific needs of the species you choose and make sure you can provide a suitable environment for them.
