Hello, I've had my 10G nano set up for a little over a month and I'm having problems with my newest addition of a Royal Gramma. The 1st inhabitant was a Yellow clown goby. I've had the goby for a few weeks now and I have still yet to see him eat anything. He actively swims around at night time hours but I have never seen him actually feed. I recently added a royal gramma and it seems to hate the goby. Actively charging it with an open mouth if decides to come out of hiding and perch in some star polyps. The clown goby is losing it's yellow color and is turning more of a pale peach. I'm afraid he will just eventually wither away and die from starvation or stress. I purposely bought the gramma over your standard damsel or clown because they claim to be very peaceful. Has anyone else had problems with Royal Gramma aggression?
