So then I read it right.
It's not just me and my superb lack of sleep skills.
Well that's just pathetic, but then again, that's why there are exponentially better forums online, such as this one! i think everyone's covered it quite nicely.
TeenyTinyTofu, here's a tip for the Walmart one. I actually have it - Great deal. Great. It doesn't come with the heater (well, the $30 doesn't. There's a $47, exactly the same, except with a heater I believe).
On the box, it says "Buy the Tetra 2-15 Heater". ... Don't. It's not very good. It's preset to be 78 +/-2 (plus or minus two.)
It hardly keeps at 76. It's always 76. or 75. Like, never 77. Don't make the same mistake I did. Lol.
Not to be edgy or anything, but there actually is a 10GAL Aquarium at walmart too! For about $36. I really really wanted that one, but, the ones at my walmart were all returned..and... ... shattered. (WHYYYYYYYYYYYYY.) Just a little note :)
