I moved him to his own tank at around 8" because I was having to feed 100-200 feeders a week just for him to get his share. I was also hoping it would be easier to convert him off live food with him being in his own tank. I havent had any luck yet. He will bump food with his nose and charge it but won't take. I've given up for now and keep a supply of large feeders at the house so he can feed daily since all the new armatus owners are catching up to him now.
