Well, I haven't talked on the forums in a long time, so I'll make the first part brief by saying I got another GSP. Well, he looks to be having some problems. All water parameters are perfect, but his left fin is not moving. Today, I came home and he was sleeping, but only problem is he was sleeping on the surface of the water, with his fin curled up. I had a suspicion of a bacteria infection, so I went ahead and started treatment with medicine. Has anyone experienced this problem or know what could possibly be wrong?
