It's a dwarf gourami, its white. I have another white one and 2 blue ones. It has a black spot at the end of its body, which its supposed to have. It just sits on the bottom of the tank, it will shoot up real fast to the top of the tank. But I thought these fish stayed more toward the top, the other ones do. This one just lays on the bottom. And it swims vertically, looks like its struggling to get to the top, but will shoot to the top too. IDK??
