Seahorses require more care than many other species of fish (and less care than some), but if provided the right care, they are easy. Unlike many "difficult" fish and corals that should never be in the hobby because we cannot provide proper care; as hobbyists we are actually able to give seahorses proper care. That being said, they aren't a "toss food in once a day" type of fish. They require feeding of frozen foods twice daily, and they require you to get a sitter if you are going to be gone for any length of time, since they will not take dry prepared foods that could be used in a vacation feeder. So, if you are willing to give them the care that they need, then yes, they are an "easy" fish; but if you are looking for something that is not time consuming, and that can handle being left alone over the weekend, then seahorses will be "difficult" for you.
