Hi Michele:

I read through the fish TB article - that's a scary disease! I'm leaning towards it not being that - the fish never had any open sores, fin problems, or spinal deformities. The red streaking that the corys had was under the skin, moved to different places on the body & fins, & looked like photos of septicemia that I've seen. The tetras never had any streaking that I saw.

How long can a bacterial / viral problem "hang out" in an existing tank with fish displaying no signs of illness? I really thought that things were OK since it has been over 2 months since last fish loss. Also, symptoms displayed by my last tetra were different than the others before, so I'm not certain it was the same problem.

Thanks again for your time!
