Eclipse 29g combo tank

[dunl]

I bought one of these secondhand, and I'd be interested in suggestions as what to stock in it. It is one of those tanks that is higher than wide or long....24" wide x 26" high (including canopy) x 12". It also comes with a built in filter, and seems to have a fairly good flow to it.

Fish, corals, etc.....or maybe even freshwater. I'm not sure what to do with it yet, but suggestions are most appreciated.
