No I didn't as it came out of a tropical tank and they he/she is with Guppies and Platys. I was told isalt kept Ich away.Not sure about the Borneo sucker and Salt, but:
What live bearers are you talking about ?
And why do you want to use salt ?
On a side note, do you know that Borneo suckers are cold water fish and "most" live bearers, tropical (and should not be kept together) ?
