Dude, id say that was only slightly overstocked and wouldnt be a problem with 40% water changes a week.
Shrimps produce tiny tiny waste. One thing i would say is to take out your betta as they dont do well in community tanks aspecially with other anabantoids (unless theere have been no problems).
Yea i do around 30-40% water change aweek and have a very powerful filter, i didnt say it was overstocked i was just stating that he/she has no where near as many fish as me and he/she has a larger tank.
