adding indian almond leaves to your water will depend entirely on how your water tests for hardness, and ph.
personally, I prefer bolivian rams to any of the others. Its only M. Altispinosus and M. Ramirezi. Gold rams, and electric blue rams are all different colors of the german blue ram, which are all M. Ramirezi. Not only are the bolivian rams easier to keep, and much easier to adapt to non-native water conditions, but in my experience they tend to have more personality, and are fun to watch.
ive read and heard many times that the hormone treatments some farms give the blue rams to make them more colorful runs a chance of making them all (M. Ramirezi) infertile. Dont remember where I heard it, though.
