I bought two BPs at the same time. My mojave was 107 grams and my spider was 139 grams. I bought them just over a month ago. Today i weighed them and the mojave is at 119 grams and the spider is 178 grams. The mojave skipped a few meals though. As long as they dont lose too much weight it doesnt matter too much that they grow slower. My normal male has gained about 300 grams in the last 3 months. He is an absolute beast and eats EVERY time.
