I have had nothing but trouble with my Swordtails. Guppies & Mollies I have no trouble. I have a 55 gallon and a 29 gallon tank. Have had fish for years but decided I wanted swordtails again and everytime I get them (usually 3 at a time) they don't live very long. I have only them in the 29 gallon wondering if the mollies were bullying them but still they aren't doing very well. Any suggestions? I use salt, I change the filters am would really like to know what I'm doing wrong as I love these fish.
