  1. Some of the fry that i gave to my sister made it back home to enjoy a nice vacation with lots of sunshine in the ponds. Odd to see how the difference in size is compared to the pondcrew.....
  2. I have often found a common water fungus(same as mildew i think) taking a liking to GF eggs but also as a secondary infection on the fry. That was during my ranchu spawn after which i upped the salt treatment of the water and the problem never came back. Anyway, if you dont have a microscope, get one!
  3. I am sorry i cant be more helpfull and you should read what i said as just my opinion. I hope you will succeed in treating them, but fry are extremely delicate which is all i wanted to say really.
  4. Sorry to say this...... But better to end it here. I have seen too many disformed fry that have been kept alive and to say you should keep feeding them is wrong! Better to humanely put them to rest, learn how to raise a good spawn without chemicals, it will take much time and effort for sure but i have done so with my fry eventually. I wish you well, remember they are what they are.
  5. Thanks for the replies! The pond crew is about 7-10cm at the moment. So not the largest fish, but for our moderate european climate it is ok i guess. These are getting used to our outdoors temperature changes amazingly well by the way!
  6. The story continues.......
  7. At 3 month you can savely assume tail that are still closed will not open anymore. Next considerations are 'balance' in their caudal fin and if the top finrays run over the top of the peduncle. They last may or may not be an issue, but is considered an undesireable trait. Dont worry if you cannot find the quality you are looking for, if you do not mind the work and enjoy breeding the fish ill bet you wil get another opportunity
  8. Very good point, it may be crucial to establish a bloodline specifically bred in the climate you are in. Reminds me of why japanese GF Kai share info and fish in certain regions and work together to perfect 'their' variety. But ok, that is completely off topic and i am discussing too much.
  9. Yes you should try and grow the fry out during winter, but to establish a bloodline for your region and climate will be interesting and rewarding. Just speaking out loud, no criticism intended.
  10. Fat content is pure energy and growth for GF or koi during summer. Good video but different climate, different rules and growthrate/hibernation protocol. A facinating hobby it is for sure
  11. Allright, i cant measure them so i´m just estimating from the pictures. Hope all will be fine, its allways fun to see those small fry
  12. I am sorry i have to say this, but your fry are behind in feeding/growth, at least i think so. Below a vid of allmost 1 month worth of feeding BBS to my sakura oranda fry.
  13. Watching with interest! How much BBS are you hatching per day? Good luck!
  14. Up front i would like to say i am never agreeing with a single ´best´ way to grow out a spawn. In research i have found there a several ways to successfully grow out spawns depending on outdoors or indoors growout. Outdoors / Green water: hard to maintain correctly but very high survival rate. / UV-C: easy to switch between indoors and outdoors. Either way, mineral balance in the water is very important, use of clay, food supplements/ Indoors /Prazi powder: I was very disappointed, yes it killed the flukes but it did harm the fish, at least this is my opinion. /japanese method: Observe, high WC's +90% , weekly filter cleaning and use of salt. This is what i am using now together with UVC method in my ponds. The fish need plenty space though. May be alot of work but i have good results with this. I personally would split up the fry and not bet on either ways of rearing fry, once youve collected experience you know what will be best! Good luck!
  15. I would keep more, remember that of those 4-5 half will be male and probaby when they are a year old half of those 2-3 will have not developed to your liking or have even died. Ive read breeders grow out about 25 fry to select 5-10 seeds from after a year of age. So if space and time permits i would try and grow out a few more of the fry. But anyway, the fry need to change their colour first right, lets hope for many bue ones!
  16. They look great! What is your plan for these? Are you just going to rehome them or are you going to try and breed a next generation?
  17. Buy a good male with breeding stars? You could also try and seperate the males and female so the males regain a milt supply, but small males do have little milt. If at all, and a chasing male is not allways fertile. If it has breeding stars it is though.
  18. If you want to select good seeds from these you are doing OK!
  19. It sounds harsh, but i tend to cull every smallest defect if i am overstocked. If you can rehome some you dont find as interesting, i would do that asap. Another way to proceed with raising fry is to move them in an oudoors tub. This will improve the fish aswell as boost their growthrate and immune system. I have a couple of ponds in the backyard now, alot less work and a great way to enjoy your fish during summertime!
  20. No problem, glad ive had a little more time to post here lately! It will take some time to find the right kind of food with a good quality fish meal. The foods i use is just a commercial fry food available in my country and western europe and used for rearing all kinds of cold water pondfish. It has a similar smell as fresh fish so it does not smell fishy at all allthough it allmost entirely is made out of fishmeal. Flukes are a pain, hope you can keep them under control! When fry are small ive had best experiences with doing large WC's(90%) and keeping a little salt in the water. Allmost forgot, siphoning accumulating waste is also very important to prevent fluke outbreaks. Any time i was not doing it enough i had flukes issues. Same with filter cleaning.
  21. I think the fry bottoming out just have a weak swimbladder that seems to have popped (excuse the word). Actually ive had no fry as of yet that floated. It think overeating or a minor bowel inflammation can cause this, i have not found a fry recovering from this. As with my ranchu spawn i also kept a 'runt' tub to see how they would develop. Like stated above, some really do catch up but do seem to be of lesser quality in the long run. Great to see your effort in breeding, next attempts will be better i'm sure!
  22. Fish can overeat but that should not give the problems you have with the fry. Try feeding less and more feedings. When fish are panting i usually suspect gilldamage, so either waterquality could be an issue or gillflukes. I had to search for the label on the fryfood i feed, both the 'colour' crumble and micropellets contain the same ingredients exept for the astaxanthin in the colour crumble. Ingredients: fish meal, fish oil, wheat gluten, corn starch, yeast, vitamins, minerals Analysis: crude protein min 54%, crude fat 15%, crude fiber 0,5%, crude ash 8.6%, total P 1,5%, total calcium 2,4% Vitamin A 12.000 IE/kg. Vitamin D3 2.500 IE/kg. Vitamin E 240 mg./kg. Vitamin C (stable) 300 mg./kg. Probably the most simple list of ingredients for fishfood, but it works, micropellets are very water stable, more then the crumble. Important when starting to feed dried foods is to soak them a bit before feeding. Just the right amount so the pellets take in all the water. This wil soften the pellets. Good luck, hope to see what will become of the fry!
  23. Hi Kath! Sheer cuteness! I dont mind the 'uncoloured' ones at all, when crossing different genepools you can expect this colour so don't worry about it. The fish seems to have a single anal fin, this i dont like, but also no dealbreaker unless you plan on breeding them..... How many you have left?
  24. These are my Sakura Oranda after exactly 1 month by the way. After the following cull i started introducing micropellets, but slowly, probably at month 2 had them completely on dried food.
  25. 50%+ proteine is what i use aswell but i do not ever use powdered foods because it pollutes the water too much. After BBS i use a 0,5mm sinking micropellet to start and a sinking 'colour' crumble 0.8mm. I do not use probiotics early on, but i have seen many grinding up hikari green or purple in a pepper grinder for fry. Mind though, i allways start a fresh system with fry so hence the reluctance with probiotics. I will post the food specifics tomorrow. The Azayaka fry food seems very high on crude ash content.
