Question: are dwarf seahorses hard to keep?
Answer: Difficult to maintain, the Dwarf Seahorse requires a small, species-only tank and does best in groups of 4 or more. If keeping only one or two, a 2- or 5-gallon tank is suitable; if keeping more than 10 Dwarf Seahorses, use a 10 gallon tank. The smaller tank size helps concentrate the food.
