That forum does take a while to approve. Just fyi, there isn't actually a ton if info on dwarfs there. There's actually more and better info other places on the internet. A couple thoughts, you're looking at hatching and enriching every day. Every single day. And feeding. They need a small tank and some way to deal with all the extra nutrients. Then there's the hydroids. Ideally every single thing that goes in the tank is dry or relatively sterile. That also rules out macros unless you can find some that will survive a fresh water soak.
Besides all of that, there are a bunch of people out there that successfully keep them! And they're relatively easy to breed. If you have the extra time to devote to feeding and cleaning I say go for it! Just read up on hydroids and what all that entails. Also, a good source for them is seahorsesource.com. They're terrible shippers so be prepared to lose a few. Usually they include a couple extra because of this.
