Tank size, and what fish (species and numbers) are in it?
How long were the neons in the tank before they started dying?
What are test numbers for ammonia, nitrite and nitrate?
What is the pH?
What is the hardness of your tap water?
How often are water changes, and how much water?
What is your water conditioner?
Are any other substances aside from the conditioner going in the tank?
29g with 7 rummy, 5 pepper cory, and now no neons.
No live plants. Had 8 neons for about 2 months. Added 5 more neons then they started dying.
Ammonia 0 nitrate 0 nitrite 0
Ph around 7.0
Water is soft
Weekly 25% water changes
No other substances in tank
