A few months ago I got my yellow watchmen goby along with two small clowns and 2 fire fish from Dr reef. All is great and all ate very well and still eat well except for the goby. The past week I haven't seen him eat anything. Normally I spot feed him and he eats no problem. I went away for a few days (had my mom feed them for me) and when I come back he just won't eat. I'm feeding rods food and pellets for the clowns and fire fish since they take that easier than rods. And the past few days it seems like he is staying out of his hole way more than normal and is staying by the glass. Any input would be great, thanks. Also I know I have some cyano currently adding more flow to the tank to help try and get rid of it.
