Yes I think its stocked maybe a little overstocked. No ram would ever work in that tank no matter which fish u took out rams are very sensitive and they would get torn apart or it would just hide and u would never see it. Are the convicts females if the cons are either both male or a pair.( Which if u have a male and a female its pretty much guaranteed a pair lol) I would remove them and get two females or some hrp there better looking and u wouldn't be overstocked IMO.
