I think it's pretty well known that you need to have a pair of Ram's before you introduce them to a tank. Unless you buy them as a pair, or raise them from juveniles, you probably won't end up with a pair.
The balloon trait is a purely aesthetic choice. I understand everyone's opinion on that preference. However, I'd like to defend the practice:
When selectively breeding for aesthetic features, multiple complications can arise. From weak genetic dispositions (susceptible to illness) to practical failure (messed up internal organs, inability to swim/eat). The blood parrot fish is often cited as an example of how horrible this sort of selective breeding can be.
However, the electric blue shimmer of your EBR's has been selectively bred to be that color. Most of the color variants in your fish tank are not the natural occurring color variants you'd find in 'the wild'. Most of us know this, and accept that there can be selective breeding which doesn't hinder of harm the animal. Most color morphs are the result of selective breeding.
Likewise, many people protest the breeding of Pugs and Mastiffs due to the genetic problems that arise from these breeds. These are examples in the canine family which have been selectively bred to the detriment of the animal. Few would argue, however, that a labrador, or golden retriever (or any other healthy dog) is in any immediate danger due to the selective breeding that occurred which resulted in those dogs. There is a large variety of color and size polymorphism that can occur in any particular species. This phenomenon is what results in the natural process of evolution (instead of us choosing our favorable genes, the impartial hand of nature decides).
This is a long winded reply simply to say that my Balloon's don't exhibit and health issues (living for 2 years so far with no problems) nor any practical problems, like being unable to swim properly. These are perfectly healthy fish, and I would encourage anyone from making the argument that it's not natural and therefor, not right, to have these fish, to look at their dog before they make that claim. Ostracizing those that have perfectly good fish which they love and care for makes those people defensive and feeling as though they need to write out long explanations on internet forums for why they love their fish.
