Kuda are actually a complex rather than a distinct species. They differ greatly in their adult size and the size of the fry. The H. taeniopterus that Dan is raising produce much larger pelagic fry and are so much easier to raise than reidi. His broodstock was originally imported from Seahorse Australia as CB pairs. Yes, they do come in a yellow morph. The newborn fry are capable of consuming prey in the 400+ micron range. I know, I am a enabler.
