You dumped them in a tank which probably had drastically different parameters from the one they were in at the store. I've read neons (and most fish, I suppose) don't do well when having a traumatic event occur like this.
yeah true.. I figure if they die, then that just helps my filter do it's thing.You probably shouldn't have tried to cycle your tank with fish, but given the fact that you went this route, you should've chosen a hardier species like zebra danios and maybe only 2-3 tops. If I were you, I'd skip trying to cycle your tank using fish and go with a fishless cycle. You can spend a month or so working on your scenery (rocks, plants, driftwood, etc.) and have a nice set-up ready when your tank is actually ready for fish.
And I think you are right. I would also add that Neons might not be harvested in a great way. They are probably stressed to begin with, poor things.You dumped them in a tank which probably had drastically different parameters from the one they were in at the store.

Thought about that. Also, tested my GH and KH today. KH is high at between 120 and 180, and GH is 0 to 30.Yeah, your fish didn't have the conditions that neon tetras thrive in and so they failed to thrive. Instead of breaking out the RO system, maybe look into fish that do well in really hard water (is your water hard or does it just have a really high pH? this is important). Even some more sensitive fish can adapt if you change conditions slowly. Neons also seem to die kind of easily though so don't beat yourself up to much. It's a learning experience! Now you know what not to do next time!
Overnight, well 16 hours anyway. Also, our power went out last night for about 4 hours and it was cold as hell in here... who knows what contributed.so the neons survived a week without a heater and when you installed one they died immediately?
