Can you keep a seahorse in a fish tank about 2 ft. long,6-7 in. around and 1 1/2 up?

Answers:
Seahorses should be introduced into a mature, cycled aquarium. Numerous filtration methods and tank set-ups can result in a healthy, stable seahorse aquarium. A seahorse tank must have gentle to moderate currents. Be sure there is adequate biological filtration and do regular, partial water changes of 5-20 percent per week as you would with any fish-only aquarium, to keep water parameters as listed below. Water parameters should be stable before animals are added:

pH - 8.0 to 8.3
Specific gravity - 1.021 to 1.024
Ammonia - 0
Nitrite - 0
Nitrate - %26lt;20 ppm

Optimum temperature is dependent on whether the seahorse species being kept are tropical, subtropical or temperate. Generally, most beginners should start with tropical species unless the tank is equipped with a chiller unit. Heating tanks is much less expensive than cooling them. Use a high quality submersible heater. Many Seahorse.org members use Ebo Jaeger heaters as they have more reliable than average performance and do not feel hot to the touch, minimizing the chance of burning a seahorse that hitches to the heater. Allow about 4-watts per gallon when selecting an aquarium heater.

Most seahorse aquarists use taller tanks. Seahorses need height (2.5 to 3 times the UNCURLED length of the animals) in their tanks to court and mate. At a minimum, the depth of the tank, excluding the substrate, should be at least 2x the uncurled length of the animal. Further, leave a path along the substrate as some seahorses courting rituals require them to scoot along the bottom of the tank in tandem. Several pairs of pygmy seahorses can be maintained in a 5-10 gallon tank (a 10G is recommended because of the difficulties of keeping water parameters stable in a small capacity aquarium. Two to three pairs of medium sized seahorses can be maintained in a 24-gallon tank although a larger tank is preferable to keep water parameters more stable.

huh?? do you know much about seahorses?? they arent just like any old fish like a guppy or goldfish. I believe they prefer a taller tank than a wide (or long) tank.
