Right on!
So anyway, pretty much softies. There are a few specific ones of other types but I dont remember them. I pretty much stick with zoas and palys. Stuff like that.
I would put a pretty deep sand bed, thats one thing i wish i would have done when i first got the tank, but i didnt know anything about the depth. And expect a temp of about 80 most of the time. That hood keeps mine right about there all the time. My moon led's were shot when i got my tank, so i dont know how they look with them haha. Other wise i would get a stunner led strip. It really makes those corals and fish pop.
Really other than that the cubes are pretty nice. Best way to go really if you want to stay small.
Oh one last thing is they are acrillic. It says glass, but its not. So better watch out for scratching the "glass" with mag floats and stuff. There is a biocube brand magnetic scrubber that is just for curved glass and so far hasn't scratched anything with me, but whoever owned it before me did ALOT of damage with one.
