Ordered 12 celestial pearl danios, 10 red cherry shrimp and 10 zebra nerites from bob's tropical plants. Almost half of the fish and shrimp were dead on arrival with a rotten smell evident before even opening the plastic bags. I am an idiot and didn't realize that the fish might have been diseased and drip acclimated them over 12 hours and put them into my tank. They died over night and took out half my fish over the next 2 days. The fish seem to start to get a swim bladder infection and start to have their tails rise towards the ceiling and die shortly after. I am not sure if this is easily treatable and would love to be able to save the rest of my fish. It looks as though their stomachs are enlarged as well.

Thank you in advance.
