Just want to clarify you are talking about an eclipse vs. Nano cube?
If it is an eclipse was it actually sold as a
SW setup? The reason I ask is
IMO the eclipse filtratrion may be good for say 3-10 small
FW fish, but is probably under rated for even 1-2
SW. I speak from experience as I tried to help my brother do a 25
gal eclipse
SW and the filtration could not really keep up with
SW.
I do not want to burst your bubble, but if it is returnable I would look at the nano cube for a few $ more. I just saw it tonight for $119 and that includes lights and filtration just like the eclipse but much better quality of both.
The other issue is that 12
gal is pretty small for a
SW set-up, but can be done. If space and $ are not a real issue then the biggest system you can afford will make you experience that much easier. In the case of
SW a larger tank to a point is actually easier to maintain than a small one.
If the 12
gal is all you can do right now than I would defiantly steer you toward the nano cube.
As far as fish what you described sounds fine for a 12Gal Nano cube(Not sure about that blenny). Eventually you should have several crabs along with some snails for a clean up crew. Actually some would say as many as 1/
gal of each as a rule of thumb. Snails and crabs do not count against your bio load.
Of course whatever you do take it slow and no fish until your tank is cycled.
Here are a couple of starter articles:

At least you are here at AA, I am sure others will have plenty of advice to offer.
Good luck,
