Floating head
Floating head: Fish are breathing, restless, and dying on the surface of the water, which is a very common phenomenon.

Cyanobacterial poisoning: The cyanobacteria in the water body multiply in large numbers, and there is an emerald green splash on the water surface, which causes the death of the fish.
Treatment method: The general algae removal product is copper sulfate, but too much will cause the death of the fish, it is recommended to use biological algae Lijing to be safer.
Dinoflagellate poisoning : The water body dinoflagellates in large numbers, and the water surface is brownish red, causing fish to die.
Golden algae poisoning: a large number of fish heads facing the shore, fish floating in shallow water, fish body out of balance.
