Hey all! Recently one of my fish has had eating problems, white poop, and is staying away from the group. After doing all my research I narrowed it down to Heximita. I don't know how to treat this entirely as it is my first time with it, any help would be appreciated such as what meds to use, treatment procedure, and what to expect with treating the fish. He hasn't eaten for about 5-6 days now and I need to get this taken care of before its too late. He is also starting to darken a little to a blue and he used to be a sherbert color! Please help...
