Since you are moving, do you know will your tap water be different or similar?
Will it be high pH, and mineral rich? or low pH and soft?
I would want to know the water parameters before I decide on what species to keep.
Some fish are sensitive to water parameters, some are not.
Some become more sensitive as they age, and come down with chronic ailments over time, in less than stellar conditions.
Rams are one of those, We often hear anecdotes about less than robust strain, but this may really be due to rams held in adverse water parameters
If the new water is soft, Microgeophagus ramerizi or Amazonian Geophagines might work, great
if it is more neutral, or slightly hardApistogramma altispinosa might be a better choice, or Geo's from west of the Andes instead.
If your new tap water is very hard and mineral rich, Central Americans might be a better choice than their S American soft acidic water cousins.
