committed suicide. She was fine this morning. She crawled up the side of the tank then let go, gently fell to the bottom and remained there the rest of the day. She was closed up pretty tight, so I figured she was just "resting". I was concerned so I just checked on her and she doesn't react to any touch. She doesn't stink at least not yet. I'm pretty sure she is dead, but not 100%. What do I do?
