And may i ask u this.
Ifu got 2+ males housed together. One has a regurg u gonna know which one it was? One get sick. Rest are likely to get sick.
Some how i do not really see this as something that is commonly practiced. But hey what do i know. I just know i wouldnt house any snakes together seeing as its hard to tell who did what and the fact that if one gets sick it highly likely u now have more sick snakes.
