I'd just like to add that keeping seahorses is an art unto itself and that they require much more attention and maintainence that can be given monthly or even bimonthly. Please don't attempt to keep seahorses unless you have done lots and lots of homework and can provide the right home and food for them.Â
On the other hand, there are many many fish out there that would thrive and provide you much entertainment and joy. Good luck in the future!!
