That depends...are we talking a dead chromis or two or something along the lines of Jonestown in my tank? These five are very peaceful and entertaining...I almost hate to upset the balance. But on the other hand, more chromies would be cool.Eh, you might be able to..might not. It isn't normally recommended to add more after the initial stocking but fish aren't all programmed the same. One of those calculated risks..how willing are you to accept potential losses?
Thanks!
