Eating changes

[Mogwai]

Ok so... just a week ago my clownfish was very active and eating until his stomach was full. Been observing him for the week and his activity and appetite decreased alittle more each day. My other clownfish has no problem eating neither does my watchman Goby and fire shrimp. Not sure what is causing his lack of activity and decreased appetite. Any suggestions are appreciated. Thanks in advance.

fish was eating before and now its not, hmnnn, going to need a lot more clues than that.

How old is the tank, how old is the fish, display tank or QT tank? People usually ask for the water parameters too. Pics usually help too.
