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
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.
