    So I currently have 5 neon tetras
    2 glowtip tetras
    3 harlequin tetras
    6 guppies and one black tetra.

    I'm I overstocked? Can I add anymore.

    You're not overstocked but you have a lot of shoaling fish in insufficient numbers.
    The glowlights, harlequins & black tetras should all be kept in groups of 6+
    The guppies if you have a mixed sex group will breed & in a short time you'll be overstocked, they also need harder water than the tetras.
    If it was my tank I'd rehome the guppies, choose two species of shoaling fish & up their numbers, have some corys for the bottom & a honey or dwarf gourami for the middle level.

    Thank you for your advice.

    Getting another tank so I was thinking about separating the males from the females, however have found a fish store that will happily take them off me.
