I have a 5 inch indo dat that I got a couple weeks ago. So far the only thing he is eating is shrimp that I stuff cichlid pelets in. He is always at the front of the tank when I am around, looking for a handout. My problem is, the gold is almost all gone. It was good when I got him, but you can hardly tell the bars from what should be gold. Any ideas on what my problem could be? He is in a 150 with only 2 angelfish and a pleco, so it sure isn't stress from other fish. Thanks for any thoughts.
