I woke up this morning, and this is what I found on my desk:

I guess my mom decided to take matters into her own hands.
I set it up (it came with a filter, and she bought a heater and thermometer from Petco) and I found a website on dividing betta tanks with plastic mesh. I made a divider, but I'm not sure if I'm using it. She also got some vibrantly colored cave thing and something called Mopani driftwood. Whatever that is. The employee at Petco gave her some media from his own tank to start the nitrogen cycle.
I'm assuming that it is 5 gallons (It's called an Aqua Culture 5) but when I tried measuring it when my sister said that it seemed big, it came in at over 6 gallons. Who knows.
I'm going to get some plants today :)
