Hey everyone!! Thanks for all the replies and putting my mind at ease! I've been without Internet for sometime and wanted to let everyone know how much I appreciate your advice. I've made some changes in lil bruisers tank. I added a background to the back and both sides in hopes that he would feel more comfortable. Was this a good idea? Since then he hasn't come out of his little nook. He has barely just had his eyes and nose out of substrate, where as usually his head and shoulders would be visible and he is actively eating. Here lately I haven't seen him eat but there are crickets missing. I hope I didn't do wrong by adding the background. Anyone else's pacman do this? Thanks!!!
