Hey, so I have been doing some research and figured out that FBT's need calcium supplements. I would like to know what the best and most nutritious supplement is. Also I would like to know when and what insects to dust with the supplement. My FBT's ages are unknown but they are about as big as a can top (The round part from head to legs). Thank you for reading and if you have any suggestions or questions about my FBT's please feel free to reply and I will tell you as soon as possible.
