Two days ago i purchased 3 golden gourami from an aquarium store (1 male 2 female). The male is about 5inches and he wont feed. He is staying at the bottom of the tank under the planted area of my tank but will sometimes come up for a breath. One of the females is sticking with him too and is also missing the food i put in the tank. Is there something wrong with the fish or am i being paranoid?
