My two year old maroon clownfish has always eaten anything I put into the tank, but he did not eat tonight and seemed very lethargic and maybe a little bloated. The other two fish ate normally (bellus angel & goby). I added the angel about three weeks ago and went from feeding every other day to every day and sometimes twice a day. I fed emerald entree yesterday afternoon and then some brine in the evening. Half way through the brine feeding, the clownfish abruptly stopped eating and did not eat the mysis today. All parameters are normal. What do you think? Thanks.
