Fish TB; how long without fish?
TL : DR version--how long can mycobacteria live in planted tank without fish, and can MTS serve as host?
One of my tanks has some sort of wasting disease. I think TB (mycobacterium), but am not 100% sure. What I'm sure of is that they waste away for weeks, one maybe for longer even, and then die. The first I thought had eaten gravel or something and gotten a blockage or something. Anyway, I'm down to two platies, who don't look good. They still eat, but don't maintain weight. I expect they will last a month if I let them. From what I've seen, euthanasia may be the more merciful route.
Basically, I dont expect to be able to save these guys, but I'd rather not lose the plants and driftwood. How long would the tank have to run without fish for the bacteria to die? Let's say I tear down this tank and replant into a different (empty) tank--how long before those plants were clear? A month? 2? A year? Are they just permanently a no livestock plants only community? And finally, will a large number of MTS affect any of this?
Thanks for any help you can give.
Incidentally: I do not "know" it is TB, it just sounds more like it than anything else I've found. I'd suspect camallanus, except I see no signs of them pooping red worms. I haven't run across anything else even close.
