I was just buying all my supplies for my new tegu that I will be getting this season from Bobby. I was adding things to my virtual cart on lll reptile ( my favorite supplier ) and I was getting my supplements and I realized there are so many different brands out there and I woud like to know which is is the best. I know Bobby claims that Zoo Med Repti Calcium is the best but I don't know if that was because it worked for him and he stuck with it or it really is the best. And don't even get me started on T-Rex and their million different vitamins. They have the liquid UV ( supposed alternative to UV lighting ), the electrolytes ( what is that ), and like a calcium and vitamin in liquid for instead of the traditional powder form. Can someone set me straight on this please?
