I use Blood Parrots with my 3 inch Dovii,the Parrots are all bigger than my Dovii,they put on a good show(all bark and no bite!!)The Parrots dont have the proper mouth to do any damage,so my little Dovii spends the day chasing them around the tank,he nips them up a bit but no real damage.I will remove the Parrots when my Dovii gets a little larger.
