Agreed. Breeding seahorses and them having fry is easy. Successfully raising the fry takes A LOT of time, money and patience. More and more hobbyists are having success, but it is still by no means an easy achievement.
I currently have quite a few young seahorses born on Christmas day. It's been 5 months of 3x a day feedings, 2x a day tank siphoning and cleaning, daily partial water changes, gazillions of baby brine shrimp the first month - then enriched adult brine - now frozen mysis. It's is very labor intensive. If you have lots of free time and not much of a social life, you have a good shot at success.
Best of luck!
