We are a unique community of Fish Keepers who seriously take our hobby to extremes and the NEXT level. The majority of our fish collections include RARE & EXOTIC Species of all sizes, BIG FISH with BIG APPETITES and BIG TANKS.

      Hi,
      I have a 4000g koi pond with about 25 koi. I have had them for 2 years now, and got them when they were 4-5", they are now 6-8". This growth seems really slow to me. The pond is in southern california. I use kens fish summer and growth formula pellets. I also have albino channel catfish that started at 3" and are 10-14" now.

      Any suggestions for a good diet for these koi?

      My channels always seem to out grow my koi. I would focus more on water change schedule opposed to feeding regimen. Out of curiosity how often do you feed?

      Hikari makes several summertime growth food. What I normal do is feed several times a day but small portions to allow them to absorb the nuitrients. Feeding a lot all at once doesn't do any good.

      Huh. How often are you doing water changes?
      I don't feed anything special to mine. Just API pond fish food. I also got my main stock a couple years ago ranging from 2"-6". They were 8"-16" when I measured this past spring.
      Were they previously stunted really bad?

      Water changes water changes. They might be too old to get growing now.

      There could be a lot of factors at play. I am not familiar with that food. Yeah water quality is very important, but you need a high quality koi food too. I have read that koi grow until they are three. If they don't have enough nutrients or protein they will be stunted

      Yes Koi can have their growth stunted by overcrowding or poor water quality. Personally I don't believe in water changes for diluting density-dependent-growth-inhibiting hormones or other dissolved organics. I'm sure these things play a roll, but not one that is noticeable to the average hobbyist. Just keep your Ammonnia, Nitrite, and KH in check, don't crowd them, and FEED THEM.
      I wouldn't give up on their growth just yet without trying a good qualilty food.
      Food is the biggest factor: good quality and feeding often. the japanese feed some of theirs 10x a day lol!
      Whatever you get, try to get 30-40% protein (watch your ammonia carefully!) from both plant and animal sources.
      Hikari makes a good growth formula, as does Hanover Koi Farms.
      Boris Gomelski out of KSU has a great article on protein content's affects on koi growth, Will try to see if I still have it....The gist is more protien=more growth regardless of source (no duh right?)

      Hope this helps and keep us posted!

      When I picked up my butterfly koi, it was about 3" at an aquarium club auction, along with some 2" goldfish.
      They were fed generic koi food May thru Oct, and not fed in winter at all, (water temps 50'F and below). kept in a 500 gal pond, a kiddy pool in an unheated basement in winter.
      In 3 years the koi grew to over 12", and the goldfish @6".
      I believe growth has everything to do with dissolved organics, and good water quality.
      I cleaned the mechanical filter twice per week, and ran a protein skimmer to remove as many nitrate precursors as possible, with weekly water changes, unless it rained.
