Saving Molly Fry
 
Several weeks back my Black/Gold Lyretail Molly had a batch of around 30 fry which I saved and put in my 12 gallon (30 litre) breeding tank and all was well with the world. A few weeks after that I noticed she was about to drop again but I thought she would be o.k. while I went interstate for a few days, needless to say when I got back she was no longer pregnant and there were no survivors. Now she is once more about to drop (fruity little devil) and rather than take a risk I have just put her in the breeding tank with the original fry that are still only about a quarter full grown.
The theory is of course that if she has them in the main tank the fry probably won't survive with the other fish around, so I'm hoping that the older fry may not be big enough to "dispose" of them......any alternative ideas would be welcomed, I don't have another tank cycled to put any fish in so that is not an option and I'm not keen on putting her in a breeding net because I don't know how long she would have to stay in it.....aaargh, decisions, decisions!

The only other thing would be to buy or make a divider.

Apparent success!!
It's now Tuesday morning, about 12 hours after I put her in the breeding tank with the older fry. I've just got back from my morning jog and thought I'd better check. Sure enough, there she was, very slim and chasing some tiny fry around the tank, obviously looking for breakfast.
I've just put her back in the main tank and had another look in the breeding tank and at a very quick count I'd say there are about 12 new fry swimming around, I'll have another count soon and post a better total then.
Part two of this operation is to make sure the older fry don't harm them.

Further news.
I don't know why I didn't think of this yesterday before I put her in the fry tank with the others, however this morning after I put her back in the main tank and went to count the results, I noticed that the original fry, although not very big themselves, were chasing the new ones around, it then dawned on me ..... I got my breeding net and hung it in the fry tank, caught the new fry and put them in it .... doh! how dumb not to think of that earlier.
I've done a good search and only found 10, pretty poor result but better than losing the lot.
Here are a few pics of the breeding net hanging in the fry tank.

Love it! Thanks for sharing them! I love seeing the babies, haha!
I was only able to save one of my mollies second batch for fry, and it ended up dying :/
What do you feed yours?

Hi Aymbar,

Those pics were taken a few weeks back and since then all but two have "passed over", the two survivors are now in the large fry tank with their older brothers and sisters.
It is a mystery why the others karked it, I've never had a problem breeding and raising Mollies before, but it's probably just as well, I've got so many little ones that I'm not sure what to do with them all.
Feeding very small fry is no problem, I just grind up normal good quality flakes (Spirulina) until it is not much more than powder and do this twice a day for a couple of weeks, after that I still feed them twice a day but don't grind it up as much, and I only give them a small amount each time so that the water doesn't become polluted with the uneaten food.
I'll try to remember to take a few more pics tomorrow and put them on this post for you.
Thanks for taking an interest.

Thanks for the bits of information, actually.
I had been using the yolk of egg to feed mine for awhile, but it was such a messy process. I am beyond doing it now, haha.
Best of luck!

Try boiling the egg, and then you can feed crumbs of yolk with some algae based foods as well.

Hey Aymbar,

As promised, here are a few pics I took this morning of my mollie fry now that they are about 2 months old.
I was surprised when you mentioned that you fed your fry the yolk of an egg, I've never heard of that one before, and I'm not surprised that you are over it, it sounds very messy. I give my fish (not new borns) a pea once a week, it's very good for them.
