Planted Tank Obsessed

The only reason it says it's for saltwater is because Innovative Marine's customer base is mainly saltwater people. Any tank rated to hold water can be used for either saltwater or freshwater.
IM makes nice all-in-one tanks and it's hard to run across any downsides from the threads I've read on sw forums. The only thing I'd be concerned about would be the flow rate. The product description says a 13-92gph pump is used. Depending on how well you can adjust the pump, you may need a smaller one so your betta doesn't get blown around, also depends on how well of a swimmer your betta is. If all else fails, you will have a pretty decent tank for pretty much whatever you would want to do with it, saltwater or freshwater, just add lights.
