I guess it depends on your preference. Short bodies are cheaper for most but not all. Some people prefer short body due to space and not needing a bigger tank. I've seen some short body flowerhorn that won on a competition esp the GB and kamfa ones. Health wise I cant say they don't survive longer than the normal size, it depends on how you groom/ care for them. I know a LFS in nyc that have a SB GB for about 8 years now, not the best looking but its healthy.
