I'm new to the marine side of the hobby, just set up a nano reef and earlier this week (June 20th) I added my first fish, a 'yellow face prawn goby' ([IStonogobiops xanthorhinica[/I]). Water parameters were good and haven't changed since adding the fish (NH3/NO2 0, NO3 0-5, PO4 0.25, salinity 1.022). He ate very well Monday night, Tuesday and Thursday, paired up with the pistol shrimp less than 24h after I put him in the tank. Yesterday I added a new fish, a 'yellow-fin fairy wrasse' (Cirrhilabrus flavidorsalis). Both fish ate dinner together after I did a 10% water change, and everything looked fine.
This morning the goby didn't come out to eat. I saw the pistol alone, and thought that was a bit strange. Tonight I saw the goby, and he looks pretty unhappy (mouth open, biting at the pistol) and refuses to feed. I put some frozen brine directly in front of his nose, he ignored it. I'm quite worried, not sure what to do - other than looking angry, he looks healthy.
If anyone has any ideas, please help, I'm at a loss.
