Fluval Spec III and Spec V aquarium fish tank on sale with FS and ebay bucks + get as low as $40.99
I saw this posted the other day and was about to buy it through Amazon, but decided to look around. It has free shipping and $5 in ebay bucks and another 8% back from some of the rebate sites out there. Still gotta pay taxes, but you can save an additional $9+ off the already discounted price of $49.99 or you can go Big Baller Brand and get the Spec V for $79 plus an additional savings of approximately $14.40+ if you go for the larger tank. There were a lot of arguments as to what can thrive in these tanks, but I read from a Betta site that they do well in 2.5-10 gallons and these are 2.6 gallons or 5 which both would be more than adequate to house a Betta.
