I'm not personally familiar with your fish stocking so I can't say whether you are overstocked. If it looks like they are crowded in there, you may want to consider 'thinning the herd'.
Keeping an eye on your water parameters will tell you if you're overstocked, water quality wise. Keep up on your water changes.
Is this a bare bottom tank?
