If you had 3 angels together in a 55 gallon tank, I'd put my money on them killing each other. Dwarf angels are normally very incompatible with each other, especially in a smaller tank like a 55 (although there are maybe one or two people on here that have successfully been able to keep two different dwarf angels together). Did you ever see any chasing, nipping or aggression among the three angels?
