My ornate finally started eating tonight! I fed some blood worms last night after I went to bed and thought my ornate looked like it might have eaten some but I wasn't sure. So tonight, I fed the others and when I killed all the lights I dropped in a cube of blood worms. I went back in about 10 minutes later and turned on just enough light to see my ornate chowin' down. I am pleased to finally see some progress.
