I have 2 males and 1 female veiltail betta fish for adoption. All in good health and easy keepers. Recently moved to smaller containers for rehoming. The orange/light red male and female have lived with other ( non betta) fish and are only territorial if they have to fight for food but adjusts ok to being with other fish if food is readily available. The other male is a jerk, I do not recommend putting him in with other fish, he will bully them.
