I'm very confused right now because about 17 hours ago I saw my zebra danio lay eggs. Now there are small black creatures at the bottom of my tank but I don't know if they are the fry because most breeders say they tank at least 1.5 days to hatch. There's a picture of them in the newbie forum but it is not very clear so I drew a picture of what they look like.

Plz tell me if they ARE, in fact, baby danios, so I can know whether I should go out and buy food for them.

Oh yes, I just remembered that I saw another female lay eggs on thursday so that would make more sense that they are her's.

Too cool! Can you remove the adults to another tank? The fry will do best grazing on the biolfilm , say of Java Moss. If the fry are freeswimming (they've absobed their yolksac and are darting around), then it's already too late to start up some infusoria. Dust from the bottom of the flakes canister. I invert the canister and tap for fifteen seconds, turn it back upright and gently tap flake-dust from the inside of the lid onto the water surface.

If you've removed the adults, you might want to lower the water level. Cover the siphon inlet with sponge. Is the filter intake covered with sponge?

Live food would be good. What do folks think? Vinegar eelworms? Microworms?
 
Baby brine shrimp if you wan live food I would think.

I got 2 z danio fry that lived a couple of years ago. They actually hatched and survived in a 15 gal I was fishless cycling. Apparently the eggs were transferred in on some plants I added from the tank with the parents about a week into a 2 week cycling process. I never fed them anything as I did not know they were there until they were about 1/4 inch.

Oddly enough, a year later I found a pseudomugil gertrudae in the 10 gal. planted tank in which the parents did their Q. Again I was maintaining the cycle with a maint. dose of ammonia.

Similarly, I have had a few lf rosey barb fry make it to adulthood. Again in a planted tank in which I added no special food for fry as i never knew I had them until they were over 1/4 inch.

The upshot is, having live plants in a tank creates the food many newborn fry need to survive, assuming they are not eaten of course. Once they are beyond that stage, ground flake works fine.

Aside to wetmanNY- I am 3rd generation born in Manhattan.
 
Microworms are the easiest of the live foods to culture/harvest it seems, but I don't think it would be good to feed them any one food exclusively.

I have been reading about some prepared foods from brineshrimpdirect.com:

These don't require any culturing or anything. I've never used them, so I can't comment on them really, but I have read good things about them. I plan to try them out myself.
 
Okay so this is my problem- I found out that they will eat the fry when they start swimming around (which they haven't done yet and aren't expected to for another two days). I just set up my other tank less than half an hour ago so there's not much I can do moving-the-fish-wise for at least another two days so I'd be cutting it rather closely.

23 g tank: I guess it's cycled, 7 adult danios, plus 16 or more fry

10 g tank: Not cycled, no occupants, sponge filter, heater, marbles layered for 2-3 layers.

Do you think it would be wise to move all my adults into the 10 g when it is ready and let my baby fry survive?
-OR-
Do you think I should let them be and hope for the best and then just breed them on purpose later on so that the fry would always reside in the 10 gallon?


Ahh! I'm so nervous! I want them all to be fine but it seems someone's got to move in order for that to happen!!

Oh, if there are only 4 fake plants is there any chance the fry will survive? Are they fast swimmers?

I looked for baby fry food in three stores and was unable to find any but I'm going to just grind up brine shrimp really fine when they start swimming because I heard that the fry can live on their yokes for three days after they hatched.
 
I would probably leave them be and hope for the best. They WILL breed again and you can get prepared now so you'll be ready the next time.
 
Oh yes, so they bred again last night, so I'm expecting MORE fry in a couple of days. These guys are unstopable!! I'm surprised they're not full yet with feedings 3x a day plus all the eggs and lil fry they've munched on. They're going to be big fish soon!
 
:p Yes, I suppose it is. I'm the last of a dying (if not dead) breed. lol. I've liked him ever since he got here in '93. 10 yrs of my life is pretty big considering I'm only 17. But he was always REALLY nice to me and he spoke Russian with me so he made me really happy and he's so hot :D Hehehee....... :o
