Believe it or not, I actually just got one like him from Petco. I saw him a few days ago when scoping out a betta for my boys but they wanted a blue and red one so I did not get him.
I kept thinking how cute he was and how I wanted him for my own and if some random person gets him, he might live in a small bowl so I went back today and he was there!
He is a delta tail all white. I have not seen any that white there but this one was. Now I just have to set up a new tank. I grabbed a five gallon glass one from Walmart but when I opened it, it was broken so I have to head back later and exchange it!!
I am excited to have my own betta. My girls have a little purple one and now my boys have a red and blue king one and I have my little white one! These bettas are kind of addictive but I have four kids, two dogs and am about to rescue a guinea pig since my two others have passed away over the last three months so I am a little maxed out!LOL
