About that $1 gallon sale, something to think about if you're going to need lights and/or a hood for plant growing:
I got the $10 10 gallon tank during this sale. Then I got an Aquaclear 20 filter. Then I realized I wanted to keep live plants and I needed a hood plus light strip.
My 10 gallon no longer seemed like such a bargain. I probably could have gotten a 10 gallon tank KIT with lights and filter included. Granted I tend to replace the filters now anyway, but still. Here is what I ended up buying:
$10 10 gallon tank from Petco
$26 Aquaclear 20 filter (I read great reviews) from Petco
$35. 10 gallon light hood from Petsmart
plus this $15. bulb since Petco Girl didn't know a bulb was already included. :( http://www.petsmart.com/product/inde...uctId=11248157
So not including the extra bulb I didn't really need, I spent about $71 for my 10 gallon set up.
You can get a whole $10 gallon kit for the price of that light hood at Petsmart (tetra brand), sure it probably has a crappier filter but some betta owners don't want a strong filter like the ones I use anyway.
Sorry to go off topic though.
