What would you do with a 75g?

[limitedslip]

Well, Yesterday I picked up a 75 gallon from a Local pet store (i wouldnt call em a lfs, more of an everything pet store) for a grand total of...DUM DUM DUM $9.47 after taxes. I guess they were replacing their old tanks with new ones, and I asked at the exact right time ><, anyway, its already predrilled with a durso pipe.

Since I dont need another sump for my 125, I am at a loss at what to do with it, I was thinkin doing another FO tank, maybe a snowflake and a lion, but Id like to see what other people would do or any suggestions on something that would be different than the norm.
