I'm asking about the two frag on the left. They're similar that both have spiky structure, and lack of obvious eye structure. In comparison the two on the right have a more flatter/smoother and have clear eye. I thought they are different type. Then I read that the spiky structure was because it's not puffing up. They look like that in LFS, from the same tank, and have always look that way. So are those their normal look (besides some tissue loss and algae), or they suppose to puff up of happy?
