If i has some mollies in a tank with some goldfish and koi carp and the mollies or guppies had ich would it be ok to treat them with salt? I mean can the carp tolerate it?
plah831 said:Yes, carp and koi (goldfish, too) can definitely take salt. They're some of the hardier fish out there. That's why, when released by wayward fish keepers, they can do so much damage to native ecosystems. They're almost impossible to get rid of!
Your molly would probably love the salt, too. I've seen some kept in totally salt water (30 ppt).
Don't know about guppies, I've never kept them.
