I bought my reed fish about 4 days ago and I havent been able to get it to eat. I called the LFS and they said it was just because it was stressed and not used to its new environment. But when I woke up this morning it was floating at the side of the aquarium, I thought it was dead so i poked it n it swam away. Then i came back later and it was there again. It cant be a swimbladder infection right? Reedfish dont have swimbladders. Does anybody have any ideas?
