I know I already posted this but no one has helped me and I need help. Long story short I have a 45 gallon angelfish tank that had some ich with salt and it has been 1 week since the last siting of ich and everyone was looking good so I wanted to add some new tetras, while there was still salt in the water. So I added 6 black phantom and 4 black neons. I got home from the lfs and put the new fish in one of those plastic breeders, and I noticed shortly after that one of my angels was stuck to the filter, so I took him off and he was still alive but couldn't swim straight he would be tilted to the side and try swimming but he would end upside upside down or on his side. Eventually after I put him in another breeder he died. Then yesterday I noticed 2 of my new tetras were doing the same thing, then this morning they were dead and 4 more tetra are doing the same thing. They swim upside down/on their side still breathing but can't move and eventually they die. My water is good: ph: between 7.3 and 7.6. Nitrite 0, ammonia 0, and nitrates are impossible to tell because my nitrate test thing for some reason doesnt work, but 3 weeks ago when I had it tested the nitrates were 30. Please help me.
Thanks
