Food for thought. 10 gal tanks, that come with a filter and a lighted hood, for $30. A few dollars more and you can get plant bulbs that fit the hood. i have bought several and divided them into 5gals. 1 fish in each. You can also get a 10 gal tank for like $12 !!! if you don't want a hood and filter. I quit going to pet store looking for tanks as they are way over priced around here.
BTW the fluval sponges mentioned in another post work great on the filter setups with these tanks, i have a sponge on every single one. :)
