Not in my experience. Pearl are usually swimming around peacefully (unless chasing each other). Does his appetite seem off? Is he being bullied by the other fish?
how long have you had it? what are the other inhabitants? Is it eating, what size tank? What are your water parameters? any new additions?
If it doesn't seem to normal to you, it most likely isn't. Answering some of the above questions may help us have enough information to give you a good guess.
if you have multiple males in the tank without enough females or only one female with one male, the gourami laying on the bottom of the tank may be giving in to stress.
