I've been observing two LMB and two different BCP eating pellets, Optimal BG, this year. Their rapid growth was obvious compared to others of the same species. All 4 of these outlier feeders were 5" to 8". Interestingly, neither LMB nor BCP showed any interest in the mealworms the BG were consuming. They only chose Optimal, which the GSF prefer and the BG reject.
