Okay, I am really at a loss here....
I still have my 25g eclipse running.... the one that is suspected to have TB in it. I put a dose of Seachem Neoplex in it before I started to suspect TB.
I did remove and destroy the rummynose tetras that were sick. So far, no other fish show any signs of disease.
But here is the puzzling part. There has been an impossible-to-remove black film of something on all the horizontal surfaces in the tank... in other words, my plants had black-something on them, but only on the top-most leaves. Leaves that were under the top leaves remained green. I thought that perhaps it was the remains of BBA that my siamese algae shark had grazed off.
However, whatever the black stuff was, it has all died off and turned greyish since I dosed the tank with Neoplex. Now, I have used the Neoplex in the past to get BGA under control, as BGA is cyanobacteria. Logic would dictate that whatever was on my plants and other horizontal surfaces was some form of bacteria. But what was it? It was not in sheets like BGA. It was a hard 'crust' that I could not scrape off the plant leaves. Now there is just a lot of hard green spot algae.
I've spent the last three hours reading everything I can find about algae and bacteria, but I am at a loss to explain this.
At the advice of my LFS, I have not yet broken down and bleached the tank. They were not absolutely convinced that TB is the problem and told me to keep watching the tank. If more fish die from TB symptoms, then I should break it down. But the rummynose tetras had lesions of some sort, not the curved spine wasting that my platies had many months ago.
I'm nearly ready to tie the purple string around my fish tank and pitch it into the nearest dumpster.
