Went to a small pet store that was going out of business hoping to find a cheap 10gal, instead I found a 15gal for 15 bucks. It's used so I cleaned it up a bit and I'm currently testing for leaks. I'm a little miffed at myself because I finally got my four tanks set up the way I wanted and I'm already planning on getting rid of them. I don't mind all the maintenance now, but I'm hoping to be in school by Feb and four tanks would be too much if I'm a full time student. So...the plan is to divide the 15gal for three of the bettas, and upgrade Nova to his own 3 gallon, either the cube or a Fluval Spec III if I get one. I'm hoping to have it up and running by mid-January but I still have a lot to get for it and holiday shopping to do...we'll see how it goes!
