If you are planning on breeding these, here are some tips; 1. Unlike most mammals in ark, during gestation time, these DO GET A PREGNANT BELLY! most creatures (phiomias, chalicos, icthys etc) just look the same. I think equus have the same thing, but im not sure.
2. if you are planning on doing a breeding program with these, keep in mind to only have ONE breeding male! if they have a male baby, just kill it, unless you are trying to get a strong male, then keep males and females, so you don't have to wait the cooldown. 3. Make sure to get the baby food as soon as you claim it! If you don't, it will just die. 4. make sure to claim the baby when it is born, unless you don't want it. When i first started breeding, I forgot this alot. Please ^ if this was helpful!
