[Brian1989]

Hi I have just upgraded my tank to a slightly bigger one so my fish have more room I have recently bought 10 neons and slowly introduced them to the water however over the last 2 days I have lost 9 of them can anyone help with this

Brian, neon tetras aren't the most durable fish in the hobby. They are very sensitive to less than perfect water conditions. They also have a parasitic disease named after them. Research Neon Tetra Disease. Did you cycle the new tank? If not research how to cycle an aquarium. Good luck.

Have never been able to keep them, always drop like flies. Cardinal tetras and green neons are far superior. I have some that are pushing 4 years old.
