There are some that will also fit in the cube I think, just not remembering which ones....the bio cube skimmer was dismal at best, I bought the skimmer to try it out and it stunk. LOL But maybe an aquaticlife or tunze will fit, they are better skimmers than the oceanic one.
Are you planning a reef tank or just fish? Do you have any issues that make you want a skimmer? How often/big are your water changes?

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.
