Happy healthy fish,
how is this achieved?
koi are a social fish and love schooling together,
a lot of koi Keepers or pond enthusiasts have unhappy, unhealthy koi so lets go over a few ways to keep your koi happy and healthy.
(1) Water quality, now theres a few aspects to this and it doesn't just mean clarity,
against popular belief, that koi are carp, thats about the same as comparing a chihuahua to a wolf even though they share 98-99% the same DNA.
koi need quality water to thrive, this means, no debris in the water, well filtered, PH between 7-7.5, lots of Aeration and surface agitation, they also love lots of water flow, helping to build and maintain quality structure.
they won't thrive in a stagnant, un airated pond or damn like a carp would.
(2) Quality food,
koi are omnivorous, meaning they need to eat a combination of protein and plant matter to be healthy,
we recommend, porpoise quick grow koi food or Orca Quick grow koi food, fed 2 times per day (at least) koi have no stomachs.
(3) Care,
stressed koi are sick koi,
against popular beleif and even further when interbred, koi dont have amazing immune systems and are susceptible to a range of internal and external parasites & bacterial fungal infections.
the best way to keep on top of this is to always quarantine new fish seperately, we use potassium permanganate bathes for new fish, 20% water changes weekly, using UV sterilisers, and avoiding stressing your koi, no harsh handling with nets, no lifting with nets etc we lift all of ours suspended in koi bags for transport.
do all of these things and you will have happy, healthy thriving koi fish for years to come!
