Well there isn't a point now. Once a fish has been infected with columnaris you pretty much infected all the fish in your tank. So now this entire tank is a quarantine tank... I fee that the female is moving about means it's calmed down but isn't feeling healthy because of the mysterious disease which I think is columnaris. I put salt to improve gill function and shorten life span of columnaris. And put the furan2 to somehow kill it. I don't expect immediate results but I would like my ray to eat. She is getting kinda milky substance on her disc which I believe is the thin strands of the columnaris invisible to the naked eye that is dying off.
