Latin name: Other names: Pathogen: Symptoms:
Fish swim belly-up (upside down),
Fish swing on their side,
Gill covers are tightly closed after death,
Affected fish will show signs of distress, loss of coordination, rapid breathing, swimming on one side or with the belly up. After death, fish’s gill arches will be pressed to the body (death by asphyxia is characterized by wide-open gill arches).
High CO2 levels are dangerous for fish as they can cause poisoning and sometimes death. Carbon dioxide is produced by fish, plants, algae, and mollusks during respiration. In the daytime, when the lightning of plants is good the amount of CO2 is the lowest, in the morning – the highest. The most noticeable fluctuations occur in aquaria with a large number of plants, with no aeration and additional lightning.
How to cure:
Poisoned fish should be placed into fresh water.
