Seahorses are wonderful creatures, but I would advise against it. It is possible but not feasible. A 110 gals is a very large tank for seahorses. It would be hard to provide the proper denisty of food for them in such a large tank. They also like low flow enviorments with lots of stuff to wrap their tail around. Most reef tanks have too much flow for them. The bubble tip anemone would have to come out, as they would be a very expensive meal for it. They are awesome fish, and fun to watch, but they require alot of time and research. I'm not trying to discourage you from keeping them, they are worth all the trouble. Just make sure you do your homework. If you want to pursue keeping them check out www.seahorse.org for more detailed information. Hope this helps.
FWIW,
