Hiya vincentchua and welcome to Aquariumadvice.

What are the water parameters (ammonia, nitrites, nitrates)? Is always the first place to check when one has problems with fish. Also, what kind of fish, how long have they been in the tank, and what size tank?

Most of the fishes are tetra. There's guppies and agle eater. All are fine. It is the cardinal tetra that's having the disease. It will appear in a small white spot on its body and slowly spread to the other side of the body and eventually, the fish is too weak and die off.
