A lot of people have been asking me lately why some people suggest aquarium chillers for seahorse tanks, and other people don’t. It’s not actually a matter of opinion - it depends on the type of seahorse you want to keep.
Different species of seahorse occupy a wide range of habitats across the globe. While many live in tropical areas, there are species of seahorse that live as far north as England, and as far south as New Zealand.
Seahorses from these temperate regions need water that’s much cooler than tropical fish tanks, and in order to keep the water at about 60 degrees Fahrenheit year round, you’re probably going to need an aquarium chiller.
Some of the cold-water seahorse specis are the Pot-bellied seahorse (Hippocampus abdominalis), the Cape seahorse (Hippocampus capensis), the Short-snouted seahorse (Hippocampus breviceps), and the Sydney seahorse (Hippocampus whitei). These species are mostly from South Africa, New Zealand, and southern Australia, which is why they need cooler water to survive.
In cooler areas, you can keep these species safely most of the year, though an extended heatwave could certainly be a problem. However, in most areas of the world, an aquarium chiller will be needed year round to keep these seahorses healthy and happy in your aquarium.
