Koi: Jumping Out Of Water

[mark4785]

Hello,

Today whilst in the garden I noticed that my smallest 8cm Koi began jumping vertically out of the pond. I immediately grabbed some food to entice him to the surface and I have noticed some black splinter like colours on his body. When we bought him from the pet shop the length of the fish was only around 5cm and the entire body was orange. Unless the skin pigment is changing naturally, should I presume that the black specks are third party objects? Maybe larger parasites?

I have come across a particular website in the past that stated Koi will jump out of the water during the hotter months, but it isn't very common and they usually won't jump frantically 3 times in a row as though relieving irritation.

I have inserted a picture below of him:



Would appreciate any pointers on what the problem may be.

My nitrite, nitrate and ammonia levels are within normal range. My PH level is 8.2 and I am awaiting for the bagged pete to reduce the alkaline levels.

Koi are terrible for jumping, no reason for it really, they jump because they can! Because they want out or insects or for the fun of it!

Had a customer who had a 16" Koi jump clear out the pond and over the 5ft sloping bank above the pond then flap its way down the garden whilst being chased and finally caught and returned to the pond!

if its just the one then dont worry about it.

fish jump for many reasons..flies..for the fun or because they have somethng troubling the gills and water quality ie not enough oxygen.. and gill problems and quality will be noticed on more than one fish.

yours looks really healthy.

I notice the koi in my local pond jump now and then it is actually pretty awesome to watch a huge 20lb fish lunge out of the water.

check the water parameters to check they are fine.

Make sure you have maximum amout of air going directly into the pond.

theres nothing wrong with the koi just abit of lack poping though

hi
If its jumping because of water quailty ,parasites or irritation, then it should also show signs of scratching/ flashing to , so keep an eye on it see what it does also watch the others to see if any of them scratch or flash.

the marks could be whats called shimmies ,there many different theories as to what causes them things like hardwater,softwater,ph,kh,gh,ammonia, food quailty and even genetics
test your water for the ph,kh,gh and ammonia.
none of my koi jump they are to fat
but i do have a comet in the goldie pond who sort of body surfs, he only does it in the evenings but only when whenever the mozzies hover over the goldie pond he does it for about 10-15 mins then stops hes the only one that does it

That must have been terrifying lol.

Thank you for all the feedback on this subject. The Koi seems to have stopped jumping now and he is still eating well so I am not that concerned.
