Hi, I have a 20 gallon long tank with a breeding pair of marigold swordtails. I was wondering wether or not a Betta would be suitable because i wanted to brighten the tank up a bit. Is the Betta gonna harass the swordtails or vice versa. I dont wanna get it if it will. Also, im not worried about the fry, I ususally get the female into a breeder trap before she ha the fry
