Well, I'm crushed, my big community tank has broken out with TB. I've no choice but to cull the sick fish :( I suspect the sudden breakout has been caused by their immune systems being weakened by a breakout of camallanus.
All of my threadfin rainbows are infected, and they've been dropping like flies. One of my honey gourami is on it's way out the door, the other is not showing signs except for loss of color, but I'm sure it's just a matter of time.
My question is, what other fish must I cull? I know that some species are more prone to it than others. I'm planning on leaving my plecos and cories be, as they aren't known to contract TB. However, I'm worried that any fish I keep will be carriers, and possibly infect new fish in the future.
I'm particularly worried about my Garra and Ram, which I've read are prone to TB, but I really, really don't want to cull, and they aren't showing any signs.
Here's what I have:
1 Garra Flavatra
1 Female Plakat
4 Betta falx (1m, 3f)
1 Baryancistrus demantoides Pleco
2 Colisa chuna "Honey Gourami"
1 Corydoras aeneus "Bronze"
2 Corydoras paleatus "Peppered"
1 Corydora schwartzi
5 wild-caught cories *very* similar to the schwartzi
1 Mikrogeophagus altispinosus "Bolivian Ram"
12 Iriatherina werneri "Threadfin Rainbowfish" (down to 6 now)
9 Albino Bristle Nose Plecos
2 Crossocheilus siamensis "true Siamese algae eater"
The betta falx are going to be QT'd and I will be monitoring them for a very long time. I don't have the heart to cull them and they aren't showing any signs.
Should I keep these guys in permanent QT? Cull them? Ahh, I really don't want to!
