What sort of Rams are people having trouble with? Different strains/color morphs are notoriously weaker than others.
I would say, in order of difficulty from hardest to easiest, it goes like this:
Gold Ram (weakest Ram, very poorly bred morph), German Ram (very picky about water conditions but keepable with practice), Bolivian Ram (very hardy and easy to keep).
If you want Rams and are willing to sacrifice a little color for a very stable fish, go with Bolivians! I love my pair, had them for well over a year now after experimenting with other Rams for months with little success.
