^^ I only have 4 leopards. They eat about 5 full size worms a day at the moment as they're growing. The draw you can see there is only 1ft square, I probably have about 100 beetles. Worms take about 2-3 months to grow to feeding size. Until I get a cycle going properly I won't be feeding any off. It doesn't take much to keep them going. Porridge oats as a substrate/dry food and half a carrot every few days to keep them hydrated. Most of the time I spend with them is moving the pupae from the worms and when they grow to beetles add them to the colony.
It's a better way to waste time rather than causing braindeath with soap operas.
