I am soooo upset and need to vent a little. I went to a LFS that is the only one around, right now, that sells fresh water flounders and long-finned gold zebra danios. I was very interested in buying these but I usually look at the fish I want for a few days even weeks before I buy them, I like to research them and make sure it is what I want before bringing it home and being a little less thrilled with it since your kinda stuck with it after that. This LFS has a 2 day 100% money back garantee and 4 day 50% money back garantee, you also have to bring a sample of your water in and it can't have any levels that are off even the slightest bit or no refund or replacement. In saying this, I like to make sure I get a "good" fish since there isn't much room for error. My first experience was buying 4 long-finned danios. The LFS tank was so over stocked, I can't even describe how overstocked, not by a few but a LOT. I asked the guy to pull out some of the fish and let me look at them in the little holders they hang on the sides of the tanks, he said no. I really wanted the danios so I told him what I was looking for and that he could pick them out but I wanted to o.k. each one he pulled out. This apparently was satisfactory to both of us at the time. I got what I wanted and got out of there feeling very weird and not very well taken care of as a customer. Two months later I go in with my husband and ask them to pull out 2 freshwater flounders from a tank that had very few fish in it, again no. I told the guy I wanted him to pull them out because the danios I bought a few months prior looked bad now (the ones in their tank, not mine). The LFS guy got very mad about my opinion of
his fish and swore at me. My husband got very upset and asked for the manager who did nothing. Needless to say we walked out without a flounder. Now I've vented, thanks for reading! My long-finned gold zebra danio died today.
It started acting odd, not swimming as much and then eventualy laying on the bottom of the tank. It got a crook in its spine, my husband described it as shrugging and looking unhappy. My question is, what is fish TB and how do you cure it? I was told thats probably what my fish had. That second trip to the LFS for the flounder revealed danios that had the same look mine now did and more than half of them were gone.
Still the tank was incredibly over crowded. No more gold ones to be found, could they be more infectable with this fish TB? Could this be something else? The other three in my tank seem to be o.k.(cross my fingers). I assume this is spreadable and not a born with kind of thing? How do I prevent the other fish from getting this?
Fish TB 
I think you are having fish tb in that case you need to put all you fish in a hospital tank and wear gloves and empty your aquarium carefully because fish tb can be passed on to humans and rinse everything with chlorine
