My hubby and I were in the pet section at a super wal-mart in the city we are moving to next month this evening and I pointed out the Betta cubes and some other small Betta tank they were selling and this was his reaction: "What is that, a Betta prison? How can they even move in those things?" Of course this is also the guy who is insisting that I need to buy the same size tank for my new boy as I have for my girl so my boy doesn't get jealous of her bigger tank. She has a 5 gallon, while his is a 3 gallon (the pet store was out of 5's at the time and I needed to buy something before his arrival, so I got the 3 gallon)
