fry often have massive dieoffs because a lot of them have deformities of some sort or another that lead to them having problems.

Are you making sure your water is de-chlorinated and temperature matched. they are very sensitive to temperature fluctuations. sp? Sorry for my spelling, I am tired and sick LOL.

I don't even use de-chlor in my fry tank. We don't have chlormines here, so I just let the water age for 24-48 hours. By that time it's the same temp as the fry tank, and all the chlorine is gone.

Are they getting enough food?

I have had 2 batches of Fry - the first lot died, probably due to over feeding.

My second batch I had approx 50. This was 3 months ago. I now have 11 left.

Some seem to die due to deformities, not growing, bent backs, hearts not keeping

up with body etc. It's normal, and very sad. I have one little fry that I had to euthanise last night due to being damaged in the filter. They are very fragile.

At present I am tending to about 45 fry. The largest of them (about 10) are ones I was not aware of that existed. I had buckets containing tank water(rain water) and floating fern (Azolla Pinnata) in my back yard. I have a back yard pond with lots of frogs.I had put over half a dozen buckets in the yard for the frogs to spawn in so that the Comets in my pond would not eat the frogs eggs and tadpoles. I had checked all the buckets from time to time with the exception of two of them. In these two , the 10 fry were absolutely huge compared to the ones I had fed. I think they must have survived on frogs eggs and tadpoles. I have of course placed them in a tank by now, and in case of those who are wondering.....the fry (and or eggs)had obviously been in the floating fern that I had transferred from my pond to the buckets.

Makes one think at times that when there is no human interference(as such) some things seem to do a lot better!

well, i had over 100, the water was perfect, and now i have none, again :(

could it be to do with the father being pretty small ? the chasing is back on so maybe soon i get another go.......

im going to let the tank dry out

and re start it before the next fry, just incase of any desease.will this work ?

I am sorry that you lost all your fry. :cry1

I am having good luck with feeding around 10 am and leaving the food in there until anywhere from 2pm to 4pm, at which time I syphon off the old food, do around a 50% water change, and then refeed again at 6pm. Leave the food in until around 9-11pm and then do another syphon 25-35% water change.

i was having to do water changes with a cup, as there where too many to use a syphon, i would have lost ten each time i did it, up the tube !

oh well, im sure i will get another go :)

Wow, Kev, I just got to read this thread!! So sorry to hear about all your babies! That is awful!! All I can say that those fry are sooo sensitive, and pretty much anything could set them off. My hubby lost almost all of his koi fry due to a too big of a water change, and has only 50 or so left from the original 400 something......

Hope your goldies give you some new babies soon! :)

i had these too. they were mosquito worms i think. or something along the lines of. i too lost about 700 fry and nearly lost my last one the other day (parents killed most of them in 2 days though). i think its that they are either deformed or some just die without a reason at a particular point.

tanya, your fry died????

Hey Kev,

i think it best to keep only a small number of fry at a time

when i started off breeding, i kept 100s of eggs and some

disease developed and they all died

but now i only keep about 12 at most in one 'tank'

not only are they less prone to die, they grow much faster that way
