Any job you stay less than two years at is going to look funny and require some sort of explanation. If you're at a job for less than six months, the assumption people will make is that you and the company were a bad fit. "Bad fit" can be interpreted as "applicant was incompetent and hired by mistake" so, having your own explanation about why you were a bad fit helps. Maybe you don't even list this job on your resume. If you're at a job for less than a year, then the assumption people could make is that you got a bad first performance review, and you're changing jobs now instead of getting fired later. If you've been at a job for at least two years, then people will assume your performance has been reviewed at least twice and that if you were actually bad, you would have been fired.
