Hatched A Couple Of Fry...

[Tokis-Phoenix]

Hi there, i was wondering if you guys could help me with a couple of questions .
Over the last couple of weeks my cories have been spawning like crazy in my main tank, unfortunately my largest common pleco always devours the eggs before i can do much about them. Earlier this week i found some eggs that the pleco hadn't been able to get to (they were behind a filter) and gently acclimatised them to a net hanging in my livebearer fry tank.
The eggs hatched very quickly, although i think my amano shrimp must have somehow grabbed some out of the net because there were many eggs missing the other day and the shrimp were busily cleaning the outside of the net.
Anyhoo, some fry were hatched this morning and i have forgotten what is best to feed newborn cory fry . I believe they are most likely albino cory fry as these are the cories that tend to spawn most in my main tank, although they could also be peppered cory fry too i suppose.
What are the best food for raising cory fry? What sort of diet should they have ideally?

I've read that cory fry don't do too well in nets and often end up dying- i can release them into the fry tank but i am worried that they may be chowed down my amano shrimp- i know amano shrimp are very peaceful critters, but it is because these newborns are so tiny i am so worried about them.
The vast majority of the livebearer fry in the fry tank are really two small themselves to eat the cory fry, and i can move the two pregnant females out of there soon. Do you think its safe to release the cory fry into the fry tank?
The tank has a fine white silica sand substrate, some planting and some cover- the only inhabitant apart from the fry, two pregnant guppy females and amano shrimp is a huge apple snail. Should i wait a while before i release the fry? I can upgarde them to a larger net- currently they are in a very small net resting on top of a breeding net frame infront of one of the fry tanks filters, the net is weighted down by a smooth pebble at the bottom.

Its a bad idea to put cory fry in with liver bearer fry. The live bearer fry grow much more quickly then the cory fry and in the end, thats not good for the little cories.

The fry will eat the yolk sack for the first 24 hours and then you would need to feed them something like microworms. Some people have been successful raising them on BBS shrimp too.

I dont like the breeder nets. I tried to use one on the last batch of eggs and it did not work well at all. I wont ever try it again. However, some people have been successful with them. Your best bet is to keep them by themselves.

Here is a topic you can read through to give you some ideas:

Inchworm helped me through my first batch of eggs and I was very successful.

Good Luck

Thanks for the info and link , i am wary of setting up another tank right now as i am not sure i have the space for one, however if i can i will do . With the microworms, what exactly are they or what form do they come in? Would Liquifry be ok for cory fry?

Thats one of the problems with the microworms. They come in a culture and you have to raise them. You have to put the culture on some oatmeal, or something similiar, and they will start to grow and you would see them in about 3-4 days. I think you can buy some ready to feed to the fry on aquabid and they arent that expensive.

As for the liquid fry, that stuff is very messy. I used it for a day or 2 and then started them on microworms. Someone told me they bypassed that step and started them on microworms right away and they seemed to do better. I think it might have been Inchworm. So I tried that on my newest batch of fry and does seem to work better and you avoid that messy liquidfry.

Hopefully Inchworm will post and give you some better adivce then I can

Thanks for all the great advice/info Barracuda518, you have really helped me out here !

Just a little update- 3 fry in total hatched from the eggs which i still currently have and are growing very fast (at about the same rate as the guppy fry in the tank).

When the eggs were first introduced to the tank, they were put in a very small and very fine net (with a smooth pebble weighting it down) suspended on a livebearer breeding net frame directly in front of a filter outlet with medium strength current.

After the eggs hatched, i kept the tiny fry in the small net suspended on the breeding net frame up until about 1-2 weeks ago when i decided they were getting developed enough (visable signs of eye's and stomaches on fry) to go in the breeding net itself.

When i set up the breeding net, instead of putting the netting outside the frame as you would normally do, i suspended it inside the frame- i weighted it down with a couple of large but very flat and smooth pebbles and a sprinking of gravel and sand.
The idea was to create a more natural fry habitat inside the net- i expect that most cory fry survive in the wild by spending their time in gravel/pebble beds in lakes or rivers etc so that they are out of the reach of larger predatory fish.
The second reason why i did this was the concern over cory deaths/mortality rates in breeding nets- i suspect that one of the main reasons is that it is due to the way corys eat, by filtering through substrate. In a net though this is impossible, and i expect a large amount of fry die due to starvation or bacterial infections in their barbels from feeding off the bottom of the net.
I hope that by providing the cory fry with a substrate of gravel, sand and pebbles, it will give them a more suitable surface to feed off.

I adjusted the filter so the current was aiming towards the side of the net rather than the middle- this was because i was concerned that if i aimed the filter current too directly at the net, the current inside the net would be too strong for the cory fry to dash to surface to breath (as corys often do)- at the same time though, i wanted the current to offer lots of oxygen as well as a certain amount of current to help keep the insides of the net cleaner.

At first i only feed them small globs Liquifry no.1 (i just squirted a couple of drops directly into the water, and did not stir it up like i would normally do for livebearer fry as this would make it wash out of the net too much before the cory fry could take notice of it).
Over the time i have had them though, i have been steadily increasing the variety of foods i feed them and now feed them morsels from frozen cubes of daphinia/artemecia, bloodworm juice, veg mix (it mostly consists of spinache) and small chunks or ground up bits of high quality algae wafers.
They are growing much faster than what i thought they would do, i am considering letting them into the fry tank itself to roam a bit free'er as the two pregnant guppy females have been moved back to the main tank now and the current livebearer fry in the fry tank are generally the same sorts of sizes as the cory fry .
I will try and get some pics of them at some point soon, although i am afraid they may be still too small to show up much in pics yet (my camera's quite old).

Sounds good. I hope you have better luck then I did with the breeding net. It was a diaster for me. Just be careful putting the cory fry in a tank with other fish. The cory fry would go great in a 10 gallon for quite a long time. Also, like you said, its very important to keep that net clean. Sounds like everything is going well, Keep us updated
