Mine are all fed in their enclosure, normally after dark (but not always). The main thing I have found, which someone already mentioned, is that for my BHP I put the rat in his tank and let him find it and he is very relaxed and never aggresive. The others all get fed with tongs and they are all alot more aggresive/excited at feeding time. Have tried feeding the others like I do my BHP but the diamond does not recognise it as food if it is not moving. I have not been bitten since they were tiny hatchlings, but then I use very long tongs now!!!
