My flame hawkfish has always swam normal. He like to sit on top of my return nozzle. He was fine yesterday swimming about. But today he sat under a rock all day and never came out. I just pushed him out from under the rock to find out that he can NOT swim upwards. If I lift him up, he just falls right down to the sand. He keeps tipping over on his side and catching himself to stand himself back up. He keeps doing this repeatedly. This happened overnight. What is wrong with him?!?!
