I would say no. Most peope only keep dwarfs by themselves because of feeding habits. Since dwarfs only eat bbs or pods and can not be subjected to hydroids, most keep a sterile tank for them. I have seen a few that keep dwarf pipes with them because they eat the same food.
That being said, most keep dwarfs in a 5 gal tank so most fish would not even fit in a tank that size.
