kiwi Posted November 16, 2008 Report Share Posted November 16, 2008 I would like to share with you my experience of breeding Celestial Pearl Danios. Three months ago I set-up two 30 litre tanks for breeding Celestial Pearl Danios. Each tank has twelve fish, a mixture of males and females. The bottom of the breeding tanks have a mesh grid for the eggs to fall through. The eggs do not adhere to plants very well as they are not very sticky. Male Danios love to eat the eggs, so you have to have a heavily planted tank or else a mesh grid for the eggs to fall through which the males can not reach. I am syphoning about 15-20 fry a week. Some weeks very few or none at all. Either they do not lay many eggs at once, or else the males are eating the eggs that have not fallen through the mesh and that have adhered to the Christmas Moss. The tanks are heavily planted with Christmas Moss (Vesicularia montagnei). To collect the eggs or fry I shake the Christmas Moss to release any eggs. I syphon the bottom of the tanks (under the mesh grid)twice and week, and transfer any eggs or fry to a 25 litre tank where the fry are raised until they are approximately 5mm in length. I feed the breeding Danios flake food, mosquito larvae and daphnia. The temperature of the breeding tanks is set at 22C and use a sponge filter. I have no artificial lighting on the breeding tanks, and I do a 20% water change once a week. The eggs and fry are raised in a planted 25 litre tank, sponge filter, with no artificial lighting, temperature 22C. The fry are feed twice daily with micro-worms or Wardleys Small Fry Liquid Food. Since there are many different batches of fry in the same tank I also feed brine shrimp to the larger fry. How I am breeding these fish is not due to any former experience in breeding fish in the past. It is rather I think more to a lot of good luck and reading how others have succeeded to breed Celestrials. So far what I am doing has been successful and I have a approximately 50+ fry.

malawiman Posted November 16, 2008 Report Share Posted November 16, 2008 Well done, they are beautiful fish. I have 6 myself and will give it a go as soon as I have my second fish room setup. Quote Link to comment Share on other sites More sharing options...

Adrienne Posted November 16, 2008 Report Share Posted November 16, 2008 well done and thank you for sharing do you have lighting on the breeding tanks or are they blacked out? Quote Link to comment Share on other sites More sharing options...
kiwi Posted November 16, 2008 Author Report Share Posted November 16, 2008 adodge. The tanks are set-up in the garage and are placed about 2 metres away from a large window, where they get filtered morning sun. Quote Link to comment Share on other sites More sharing options...
Luke* Posted November 16, 2008 Report Share Posted November 16, 2008 nice going thanks for sharing good info there. i have also read that doing 50% water changes every day or every other day will increase the amount of fry you get. Quote Link to comment Share on other sites More sharing options...
kiwi Posted November 16, 2008 Author Report Share Posted November 16, 2008 Thanks for the info about the 50% water changes. The breeding Celestials are over 2 years old and maybe if they were younger fish they may lay more eggs! The first batch of fry are now reaching breeding size, so it will be interesting to see if they lay a larger quantity of eggs. Quote Link to comment Share on other sites More sharing options...
caserole Posted November 22, 2008 Report Share Posted November 22, 2008 I have found like all danio's a pair in the act of spawning can/will be disturbed by other males. As Cpd's only produce 40-50 eggs(I have never had more then 48 eggs produce per spawn) a spawn, it will (unlike other danio's which produce well over 100eggs) seriously affect spawning success. My best results have always been using pairs in 12lt tanks(200x300x200high). If feed bbs and other live foods a female would spawn at least every 10-14 days (breeding traps were used, with a small clump of spawning moss above the middle of trap). I had major *&$% hit the fan many months a go now and lost close to 100 coloured up fry + adults breeder. I've only just replaced my breeders.

malawiman Posted November 22, 2008 Report Share Posted November 22, 2008 How do you tell the difference between male and females, if possible? Quote Link to comment Share on other sites More sharing options...
Luke* Posted November 22, 2008 Report Share Posted November 22, 2008 hey stu fantastic info thanks mate.. i actually just read in a book it's best to spawn danios in pairs so that reaffirms that hope this helps malawiman: Quote Link to comment Share on other sites More sharing options...
malawiman Posted November 23, 2008 Report Share Posted November 23, 2008 Cheers Luke, looks like I've got 5 males and one female. Anyone have some for sale please let me know. Quote Link to comment Share on other sites More sharing options...
TM Posted November 23, 2008 Report Share Posted November 23, 2008 Anyone in Chch with these, cool wee fish. Quote Link to comment Share on other sites More sharing options...
kiwi Posted November 25, 2008 Author Report Share Posted November 25, 2008 Thanks for the information about breeding pairs only. Last weekend I collected 50+ fry in my setup, so while it is working for me with more than one pair in a heavily planted tank I am happy.

caserole Posted November 26, 2008 Report Share Posted November 26, 2008 That's the thing with spawning fish. "If it works and your happy > no need to change<" Good Luck Quote Link to comment Share on other sites More sharing options...
kiwi Posted December 6, 2008 Author Report Share Posted December 6, 2008 Due to my inattention, I have lost a large number of very small fry from a later spawing to the larger fry from my first spawning. It seems that larger Celestials eat the newly hatched fry. I am now seperating the larger fry into another tank from the newly hatched.

kiwi Posted February 4, 2010 Author Report Share Posted February 4, 2010 My project of breeding Celestial Pearl Danios is still on-going with average success which I am happy with. I have refreshed my breeding stock from last years fry and I expect good results sometime next year. Here are a couple of pictures one of a breeding pair the other is of a few days old fry.

phoenix44 Posted February 4, 2010 Report Share Posted February 4, 2010 That is one beautiful fish. How do they do in water that is 30 deg C? Quote Link to comment Share on other sites More sharing options...

kiwi Posted February 4, 2010 Author Report Share Posted February 4, 2010 Personally I have never kept them at 30C. My fish are kept between 24-26C. Quote Link to comment Share on other sites More sharing options...
Luke* Posted February 4, 2010 Report Share Posted February 4, 2010 nice work good to see you're still at it Quote Link to comment Share on other sites More sharing options...
caserole Posted February 5, 2010 Report Share Posted February 5, 2010 30C is way to hot for them, they like it in the high teen's to mid 20's. I found they were at their best in the low 20's - (21-23C). Keep up the breeding KIWI Quote Link to comment Share on other sites More sharing options...
Jennifer Posted February 5, 2010 Report Share Posted February 5, 2010 How do they do in water that is 30 deg C? Hmm, I couldn't see anywhere that kiwi said 30 degrees.... The temperature of the breeding tanks is set at 22C ... Personally I have never kept them at 30C. My fish are kept between 24-26C. Anyway, in last October's PFK magazine, there was a detailed article about breeding these and they also said 22 deg C so it sounds like you are doing everything right kiwi. Apparently the author kept them outside until winter (the the outdoor tank got down to 8 degrees C!) and when he put them in the warm breeding tank they immediately began spawning like crazy. Great article btw. Quote Link to comment Share on other sites More sharing options...
phoenix44 Posted February 5, 2010 Report Share Posted February 5, 2010 no jen. i wanted to know IF they do well in 30 deg so i can get some for my tank sad for me though. Quote Link to comment Share on other sites More sharing options...
