Pearl danio fry??

[Tokis-Phoenix]

Ok just now i was looking into my 10gallon tank which up unitl recently housed 2 pearl danios that i bought originally to help cycle my 50gal when i got it ages ago but they caused too much trouble with the guppys so they ended up in my 10gal while i found a new home for them(which i found about a week ago).
Anyways, right now the tank houses a 2inch common plec(yes i know he will outgrow it, he's only in there to help keep it cycled) and i was just looking at the tank and there are LOADS of fry.
They've gotta be pearl danios cos apart from the little plec no other fish have been in there, thing is though, apart from corys i have never rasied non-livebearer fry before and i was wondering wether they need any special requirements? Like different foods or somthing?
I just feel totally unprepared for this kind of stuff cos i didn't even know that i had a male and female danio in the two; they were sold to me as both male.
The fry are realy cute; look like tiny miniture glass catfish )

Anyone...?

Oh I'll do it......well done Tokis-Phoenix!

Kidding. Danio's often have loads of fry because in the natural world a lot of them wouldn't survive to maturity.

I had Leopard Danio fry once, and there must've been several hundred hatched in my 5G, my breeding tank. Through as much care as I could muster, I had managed to raise about 35 to juvenile stage, and now have about 10 teenagers.

So, congrats once more, and good luck. I know you can beat my score.

Is there anything i am supposed to feed them in particular? I mean, they look so tiny i don't think they're bigger enough to handle anything bigger than a peice of dust...
Are there any tips you can give me for keeping them alive? Do they prefer any particular temperature?
Geez, im gonna get realy paranoid about chucking them accidently away via water changes...

Would help if I give some advice wouldn't it?

Don't try and remove the fry, because they're too fragile to move. If you do, only use a very fine mesh net designed specifically for the job.

Fry can be sucked up a filtration unit, and washed out by the exit vent. Since they're fragile they can be damaged by this circulation. So try and block the intake vent with some type of stocking.

Feed fry with small food such as newly hatched brine shrimp, as I've heard. My trick? I use mashed maggots from the fish-shop (I know, it sounds disgusting).

Don't introduce them to the main tank. Trust me, it wouldn't work.

Hope this helps!

Cheers for the info, i found it realy helpful i shall keep you posted in case anything interesting happens, how long roughly will it take for the fry to grow to say a 1cm?

From now to the next few weeks, you will see a change in fry length, and a slight increase in thickness. (200-300+)

From then on, the fry will start bulking out more so, with a slight increase in length. (100-200+)

Thereafter, things may seem a little crowded. If you think this is the case, the option is for you to upgrade the tank size. Personally, I've noticed when I did this the growth rate increased dramatically. (75-125+)

You will lose fry during this time, through no fault of your own. So prepare yourself that not all fry will make it.

After about a half-year, as for me, I then introduced them into my main tanks. You may need/want to do the same. But be careful, other fishes may still see them as potential snacks.

The numbers in brackets are my fry counts at each stage.

Good luck, Tokis

Oh, about 6-months in. Perhaps mine didn't want to grow up
