My boss buys the what he feels are the saddest/ugliest bettas from Walmart for the university to teach freshman how to set up a behavioral study and to give the bettas a chance at a home. We give them out to students after the studies are complete. I ended up with the two that no one wanted.
Veil (original, right?) was a last-pick Walmart baby with the common blue body with pink caudal fin coloration. Lived 1.5 years but was lost to a sudden onset of a mystery disease. Loved wedging himself in between lucky bamboo roots and was the calmest of my four boys. The world won't notice it's another what most of you would call "boring" blue veil tail short but my world is a whole lot small all of the sudden.
His brother, also a last-pick "boring" red veil tail from the same Walmart at the same time, doesn't know what to do with the extra space. Through our loss he now gets to be able to reign in his own 10 gallon. I took out the divider after staring at an empty tank half for a few days, but he seems to stay on his original side, only periodically checking out where his brother used to be. Weird.
