I keep my Veil Tail in a 10g with 5 White Cloud Minnows. He chased them around a bit at first but now he leaves them alone all together. I have plenty of floating plants for my Beta to swim in, as well as small rock caves. He spends a good deal of time exploring while the minnows spend their time swimming in the filter current. The WCM were quite young when I bought them and now they are about an inch size. So far so good
