So when I picked up fish for my new build I bought 4 2 clownfish, a fairy wrasse and a blue throat trigger. All these fish were healthy and eating at the store exept I did not see the trigger eat because it was hiding. I bought it anyways thinking the fish was healthy and that it was scared to eat. So all new fish have been out swimming and eating live brine shrimp, pellets and LRS except for the trigger. he rarely moves from his spot but when he does he moves from one hiding location to another. He is in a BB tank so i can see exctly where he is and he is breathing and sometimes hovers in his hiding spot. Got him 4 days ago and he has yet to eat. should i be concerned yet or is he still trying to acclimate?
