Oxygen Deprived

oxygen-deprived

Cause :
Oxygen deprivation is caused by a lack of water aeration, overstocked fish and/or high water temperature.

Prevention :
The use of airstones can prevent this problem in most cases. Only stock your aquarium with 1 inch of fish per gallon as a generally rule (some fish require different oxygen levels, such as goldfish). Reduce aquarium temperature.

Symptoms :

  • Most fish in the aquarium will be at the surface gulping for air.
  • Fish will lose color
  • Less energy

Treatment :

  • Provide an airstone
  • Reduce fish population
  • Create surface agitation with filters or water pumps
