I think my tanks was exposed to Columnaris. What to do

[kymob]

I have had a few bettas die unexpectedly space out within a few mounths from each other. So frustrated not being able to figure out what the reasons for the deaths. . This last betta I treated for one month with metroplex and kanoplex ( spelling is incorrect) one medication at a time for a week then switched to the other than together. No improvement what so ever. I made a special mesh encloser with a shelf that allowed him to rest and easily get air. His swimming was bad but the whole time could eat. soaked his food in medication as well as added to water. I m sure I gave medication correctly got advice fo very knowledgeable fish person. He never improves but did to get worse. Eyes looked horrible with white cotton-like thing from his mouth and eyes. and a golden color curtin it was Columnaris. I assume the other bettas had that too.

My question is: Knowing it is continuous and I definitely used utensils I cleaned with the sick fish. If my other fish show no signs of Columnaris. Do you think I should still treat my other ten tank as a precaution? If so I would put all the bettas in one tank in an individual floating mesh encloser I made if t is ever an outage that happens from bad weather. Would love a recommendation.

I have little experience with this disease. I only learned of it last week because my cory died with it. I was told that as long as his body wasn't grazed on by others, it shouldn't spread. But that was only because I removed him as soon as I noticed it. My advice to you, quarantine all and any fish you think may have it and treat them for it. This should help stop the spread to any other fish.
