About Nov-12-Fry-batch :
Due to holiday-week here, my house got busy, we are not Christians but we kinda celebrate the week by doing small get-together, shopping, catching family time , my b-day is dec 23 , etc etc. So, it was impossible to even look at the bowl and see how fry are doing, forget about taking total care, I still somehow managed to see my goldies spawning on mop on dec-25.
But this Miracle bowl kept getting cloudy no matter how many times I attempted to clean it and do 70% water change , it smelled awful when I lowered on it , I threw plants off, still it smelled bad and to stop fry's dying off at bottom, I transferred them to a plastic tray (12 inches x 10 inches) but I was not able to keep that clean this tray too (fed them more i guess and couldnt sponge off the remaining food) so fry's kept dying (atleast 1 per day) but since past 2 days, I have finally managed to clean it up regularly with water-change from main tank, I had to finesse the technique of cleaning the bottom of tray.
Now 17 fry are left, I am sure by another month I will only see 2 or maybe 5 of this batch since I managed to only catch ~ 35 eggs.
Still I learned a LOT. googling was not that much of help as there are v few posts around giving full 101 on goldfish-breeding and ofcourse the handbreeding thing is not even worth watching/reading, so forget bout learning from it.
NOW in this fry batch, I saw some fry realllly struggling to swim , so I assumed maybe they are sick or damaged and will die off, I tried to take a closee look and I see the ones wiggling LOT to go around are COMETS, so as suspected my Goldie-pair is not purebreed and mix of fantail and comet, FanCom? ComiFans ? lolz so this becomes sport breed and not pure breed. BTW the comet to fantail ratio is surprising, ONLY 3-4 fry's are comets (single vertical tail) and others are all fantail. Lets see how this goes.
About Dec-25-Fry-batch :
I had replaced a v big spongy mop on the tank week after my first fry-batch, so I saw this spawning activity on Dec 25, this time I took the mop after 5 hours because I could not get time to remove it early, this might have been more benificial actually because the milt spread by male must have properly spread in tank, thereby fertilizing almost all eggs as compared to what I did first time.
I had already purchased extra plastic tray's so I placed this mop in new tray, roughly 16 inches x 12 inches and after 48 hours, saw some eyeing up of eggs, I tried to regulate the temp in this big tray by using aquarium heater but as the water was not circulated by any power-head, so it was warm only in one corner, I had no time to sit near this tray and move heater around, so i forgot about it and let nature do its thing.
It was nearly 5 days and I was seeing PLENTY of eggs (they did not go spongy so were fertile) but not hatching. This really confused me making me wonder what to do but i did not throw this mop off because I read on google that goldfish fry hatch in 24-72 hours.
Then suddenly after new-year night, temp. here went warmer (to a comfortable 29c) and on morning of Jan-1, I saw plenty of eyeing up in mop itself, so i moved this mop yesterday to another 12x10 tray.
Today I see the tray filled by eye-lashes(fry) trying to move and dash etc etc, They are TOOO many to count so i am guessing they are around 200 or even more actually. so lets see how this batch goes too. Wish them luck.
Will try to keep update on this, I am really not sure how will I take care of this because of work-related issues but lets see.
