I'm an unwanted guest on your dish my first letter away makes me a fish my last letter away and I am not anymore only my middle is just like when you compare

Black as night, I watch and wait Clever mind, but dark of fate I feast on secrets, scraps, and grime If too many of us gather it might be a crime

I am a creature of the night, add one letter and I cover you, remove one and I am hurt

With zero limbs I have a foot. Can't be called lazy though I stay put. You'll often find me at the range. I am not stoic but my face won't change.

I am a ghost that clings to stones, a whisper born from breaking bones. The sky must bleed to call me near, yet I am gone before I’m clear. I do not live, I do not die, I only breathe when earth will cry.
