Two male betta (Glen Cove)

Description

I have made a mistake and bought two male Betta fish , had them in the same tank , a bigger one I have , and one of the betta bites the other one . I have a purple and blue which is the most aggressive one , and I have a silver with orange and blue , he has been recovering from that. Right now I separate them and I bought a 6 /2 gallon tank . But I do not want to keep them because they don’t get along with other fishes and they killed the ones I had . So I am giving them away for a small fee , and even for free if u are really serious.
