I believe my tetras may have Columnaris. 2 died, 3 are still alive. I had guppies in the same tank about a month ago and they all died from suspected Columnaris. I would like to get my nerite and mystery snail out of there along with 2 Amano and 3 live plants. I only have one other tank going right now and do not want to contaminate it. Will moving those things over contaminate it? If so, can I eventually move past this and get them into the other tank safely? How would I go about doing that?
