Neon tetras dying.. hellpp

[Vinodh]

My neon tetras started dying from an hour ago.. the temperature was around 60.. so i started the heater to make it around 70.. but they still keep dying.. just bought them y'day.. What may be the reason?

Did you test the water parameters?That might be the case.How big is your tank?

What are your water parameters?

How long has the tank been running?

Constant temp is more important-- so jumping ten degrees in a short period of time won't do your fish any favors. You'd be better off raising the temp over at least 12 if not 24 hours.
