I have had my Volitans for about a year now and until about a month ago he has stopped eating. Before that, he had a healthy appetite. I went to AD the other day and the crew advised I try live foods since I had tried other conventional methods of feeding (i.e. food on a stick, food soaked in garlic). I just tried feeding live ghost shrimp and he still wont eat. He stalks the shrimp like he used to do, but he will only "jab" at the shrimp but not make a full committed effort to feed. He doesnt open his mouth when he jabs.

Nitrates in my tank are a bit high, about 60, but all other readings (except phosphates-no tester) are within acceptable parameters. Any suggestions, ideas, concerns would be much appreciated.
