Small Fish?

[SparkysBois]

Hi, About 3-4 months ago one of my female guppies had babies. I gave most of them away but kept a couple of females (my tank is female only). However, one of the babies seemed to grow really slowly and while the other babies are quite large now, it is only half the size of them. It is very skinny, but always eats. It also seems to always be moving a lot faster than the others (fins always moving frantically). I am wondering if something is wrong with it, if it seems to just be a birth defect, or if it's just unique?

some are just smaller than others. if it is really skinny try treating its parasites.
