I took the wife today to our LFS and she saw a community tank of 6 EBA in one of their display tanks. She instantly loved them we have one right now but she wants a community tank of 6 Is this doable in something 4ft? Or to please the lady would a group of 3 with say 2 Bolivian rams and a Angel be a better option. Also always wanted to know are these hybrids? I do not see much literature on them during my Google searches.
