My fish are dying one by one and i dont know what it is.

2 days ago one of my neons died suddenly out of no where. Swimming around normally and happily the night before. I woke up the next morning to find him dead so I did a 30% water change. That day the neon died I saw my black lace angel in the corner not moving. But he was never really social so I didnt think anything of it. The next morning he was dead floating around my tank. I took him out and wanted to test my water but couldnt because my dad had moved it and he was a away on a trip. Next morning (today) I find my zebra / blue angel going around in circles frantically. I put him in my qt tank, and life left him in a couple of minutes. I'm doing a 50% water change now. Oh and my zebra was swimming around happily with his other angel bud yesterday. What I did notice was that the nose was red. So what's wrong with my tank? I don't want all my fish to die. Honestly. I can't keep doing this. Its hard for me to see my fish die and every time I have a wave, it makes me scared and not want to take care of fish anymore.

 

Do you have a test kit?

Yes I do but my dad moved it and I cannot find it. Ive also tried to ask him but he says "I forgot"

It is hard to come to a conclusion with out knowing what the water chemistry is.

 

wrong thread

 

I'm sorry for your loss. It's rough when water babies die or suffer.
As soon as you find your kit let us know the results and we will do our best to help you.

 

Sounds like Ammonia spike. At least in my experience finding fish dead over night was due to Ammonia spikes.

 

I did a water change for 50% and everyone is doing well so far

Maybe you add some Prime.
