"First off this is a great setup. I bought the 50 gallon. I do want to make clear the filtration system is awesome, note that the internal system does take up room in the tank. So you have to make the choice of having a tank with all kinds of stuff you can see, and hanging out the back and top ie; filter, heater, etc, or hidden as with this tank. It comes with a lighted hood, and you will need a (20W) lamp.
I suggest looking at the companies site, and researhing the filter system, as well as reading the tech info on water levels in the tank. (casco group makes these, google it).
This tank would make a great tank for any "jumping fish" as it's pretty escape proof.
Basically to get a nice setup you'll need stuff like gravel, heater, plants, and other decorations, an air pump to connect to the oxygen input in the wet/dry filter system. These tanks are well oxygenated, and other items added that put air in the water are not needed unless you want them for visual purposes only. Or a backup oxygen system should one airpump die if you have dual pumps.
Also would like to note the pre-filters are re-usable, just wash off in the hose, and replace when showing signs of wear. (low cost maint wise will pay off in long run versus many filter systems you replace monthy for $5.00 and up)
If you don't mind losing a bit of real-estate in the tank, but having a beautiful tank without all the contraptions, these are for you.
