There are people everywhere that want to mix different species of reptiles and amphibians together to make some sort of jungle for their animals but many of these keepers fail to recognize that mixing species is a horrible idea that can only be left to people that know what they are doing-people that have studied exactly what is needed to be done in order to actually keep these animals healthy while mixing these species. I have summed up what I know so that you won’t try to do this. 1.One problem is that each individual species need their exact environmental requirements that are found in their habitat. Abiotic factors such as physical characteristics and biotic factors together make up a niche and with specific factors make up single specie’s niche. Species are only able to live in environments that vary accordingly to their specific niche. Even within different environments with the same climate, there are multiple niches that are present. It is extremely difficult to duplicate these factors into a small terrarium and at the same time, keep these animals relieved of stress. Different species need more room to get away from each other to hunt for their own food. Because of this, terrariums need to be very large and even harder to maintain than those of only a single species. 2.Also, larger cage mates usually “Bully” different species for food or shelter. A large enough difference I size can also lead to the larger of the species devouring the smaller other cage mates. Some animals have defense mechanisms that actually activate whenever it is harmed. This can lead to the injury or even death of an animal in your cage. Different species may not recognize the other specie’s “warnings”. A misunderstanding can lead to an injury for an unexpecting species. 3.Different species develop differently than species living in another niche. They develop immunities to viruses, parasites and diseases found in their specific niche. Although they may be immune to it, it may be deadly to their coexisting cage mates, who have no immunity towards it when introduced. I know that we have all seen different species in the same tank online or at your local pet store but let me tell you that those people don’t know what they are doing. They only want to show off their “Mini-Jungle” or save space to sell reptiles without the least bit concern for the animals’ health. If you really want to appreciate your animal and give it the best possible chance of living Happily, Don’t mix species. Please listen to this information.
