Unfortunately, the best selection of bettas in my small northern college town is at the local Walmart. It really saddens me when the bettas are suffering in those tiny little cups for such a long time. Many times, they're in cloudy water, or just lying on the bottom, looking so depressed. A lot of the time, they're missing scales on their heads, probably from rubbing up against the sides so often and the bad water quality.
But, however, I can't help but to wander over to the fish isle whenever I go, just to look at all of the different kinds. I bought my Crowntail, Odysseus there in October. He's a beauty! Navy body with emerald and red fins. He recently just got upgraded from a 1 gal. to a 3 gal. Spoiled little prince. My roommate, an experienced fishkeeper, recently purchased her first betta this week from Walmart, a feisty red fantail that goes by the name of Moriarty. He rocks out in a round 3 gallon tank. His color is a little pale, and I noticed he was missing scales on his head. I loaned her some malefix to help the healing process. I'm happy to see the tips of new scaled beginning to grow back. He's gonna be gorgeous in a few weeks!
