I agree that by now your tank has already cycled.
I started with cured LR
, and bacteria suppliments in each my tanks as well, and they all cycled within a couple of days.
Of course, you're welcome to add a little food/shrimp for the bacteria to munch on as was mentioned above.
Covering the tank with glass is not recommended for the reasons that you've already read about.
As Lindsay suggested, if you are going to keep fish that are known jumpers then get a sheet of eggcrate from Home Depot.
They sell it for $10 a sheet, but if you can find a piece that's been cracked you can ask the manager for a discount.
(I got a sheet that was only missing 2" for less than $5)
Congrats on the new tank and being mature enough not to rush it.
With that kind of cautious attitude you're already two steps ahead of most beginning aquarists.
Oh yeah,... Welcome to AA!
