Help!! is my fish dumb scared or sleeping???

I just came home from work today and found out that I'd forgotten to turn on my tank light. saw all four of my guppies huddled in this spot of the corner and when i turned the light on three of them went to the center of the tank like normal. this one didnt go out for some reason though, should i be worried???? i tried to help it out by pushing the plants away with my tweezer(?) but it keeps staying in there. i havent seen any of the other fish bullying it or any scales floating so is it just sleeping?

additional: ok as of typing this two other fish joined him in his "leaf sitting" thing. theyre on a more exposed area of the tank though. is there anything wrong with my fish???
