My long-term goal is to get a couple of breeding pairs of the Sunburst variety from Ocean Riders (Hawaii-based). I want to be able to raise fry and help support the desire for people to have captive-bred, healthy, frozen-food eating seahorses 
Anyways - to start right, I was hoping to just go with a 30G tank. I realize the water parameters take longer to get out of wack with a larger tank (I currently have a 75G and a 20G, have done both fresh and saltwater for many years). There was a cute little bowfront 26G for sale, and it doesn't have that stupid divider bar at the top (I want a pretty large refugium to hang off the back), and it's 21" tall, meeting the 20" minimum. There's also a 38 that's 21" tall, and a 45 that's 24" tall. I like that the 45 is 24" tall, but that's mucho $$ in sand and live rock (and it still has the stupid divider). Plus, since I'm a renter, the smaller, the easier to transport. At the same time, I want to have *optimal conditions* for breeding. All this is weighing in heavily on my decision for just what tank to get - and while I definitely have a desire to run out there and buy one so I can start the cycling process, I want to make sure that I won't regret it in the future.
I do not *think* filtration will be much of a problem in even as small as a 26G tank...this is why: I will have plenty of live rock, live sand, a good filter which I will probably debate long and hard about later, a protein skimmer, a really good 'cleaning crew', uv sterilizer, and a refugium. The tank will be cycled and I have a couple of damsels that have been in my 75G for 8mo+ now that can be used to make sure ammonia is being taken care of properly. I also have good compact fluorescent lighting with separate blue and daylight bulbs that have individual cords to be on separate timers - this would fit that 26G nicely
There will be a ton of other stuff I wish to have input on in the future, but for now I would just like to get a darn tank up and cycling!
Btw - what filters DO you use with your seahorses (please include tank size)? And does anyone know how well the skimmers that are built in to hang-on refugiums work? The refugium I'm interested in is - http://www.marineandreef.com/shoppro/CPR_refug.htm
(the large is the only one that comes with a skimmer)
Thanks!
