The only seahorses that can be kept in a 6 gallon is dwarf seahorses (Hippocampus zosterae)
Pretty cool little fish. You'll need to consistently hatch fresh brine shrimp. They can only eat Baby Brine Shrimp not adult (no nutrition). Supplementing with pods is a good idea too. if your lucky like me, you can get the adults to eat mysis too. Biopure mysis tend to be small enough in most cases.
Read more on them before making that decision.
All other seahorses need a larger tank. The taller the better too.
i dont think its a good idea to get this tank for seahorses...This tank is good for dispaying corals. I had a small clown in there but he is now in a 12 gallon.
