my female guppy is highly pregnant. I moved her to her own tank for the time being, and she has been showing signs of labor for a few days now. (Shivering, hiding, barely eating, etc.) now I stopped to check on her before going to bed, and she is shaking to the point she looks like she is having a seizure. Is this normal? This is my first time owning guppies so I want to make sure she’s ok.
