I like these beautiful cardinal neon fish but got a problem.
Every time I bought this fish, I listen to the advise given by the shop, like
mix the aquarium water with the fish bag water for a while, Change half of the water in the aquarium before add them into the aquarium but still after 2 or 3 days they start to die. First their tail drop off then they died slowly. What is the problem and how to solve this.
