I agree with Lupin, they are a defective strain of molly - they are NOT genetically engineered. Many types of fish - tetras and parrot fish especially, are tattooed and dyed, it is not a practice particular to balloon mollies. Balloon mollies are a product of selective breeding and while they are prone to swim bladder disease, you can prevent this to a certain extent by including veggies in their diet and pre-soaking their food. This also might help with breeding.
They are an excellent choice to keep with mollies as they are closey related and like the same water conditions. I have had three for two years now with zero problems, and they are great fish - a lot of fun to watch, big personalities, and everyone who sees my tank notices them first.
Last, many, many fish commonly kept are the result of selective breeding based on defects/mutations - the expensive strains of bettas, fancy guppies, lyre tail mollies and sword tails to name a few. There is always a trade off - most don't have the life expectancy or the hardiness of their wild caught cousins.
By the way - balloon mollies are totally cute. My fav by far. Treat them right and they'll have a very happy life - and a planted 55g sounds great!
