What do Glofish Zebra Danios Eggs look like?

I think my glofish zebra danio might be pregnant, so what do the eggs look like? so I can watch out for them. Also I am not entirely sure how to tell if a female is pregnant. So if you know please help me out.

Thanks

Hello! I found this on the internet... along with more statements just like it.

"An extremely easy way to get some Zebra fry is to set-up a small tank of about 5 to 10 gallons, install an undergravel filter and use large pebbles instead of normal aquarium gravel. Let the adults stay in this tank for about a week, take them out and start feeding all the fry you will start finding in the tank. This works well because Zebras spawn just about all the time, but they are such avid eaters of their own eggs and fry you never get to see the fry. The large pebbles allow the eggs to fall deep bettween the cracks so the adults can't get to them. A lot of people use glass marbles instead of pebbles with equal success."

Good luck!

The only problem with that is I don't have a second tank

lol yeah, same here. I'd say, the marbles are a good idea... even if you put a small layer on top of what you already have... that way they have a better chance of surviving. Just keep vigilent.

Unless your tank is INSANELY overplanted you will probably never be able to grow out any danio fry of any kind, as long as they are kept with adult danio. Furthermore, if you feel the urge to breed danio, here is how I did that recently: I used a 10 gallon tank, but you could transfere the idea to any sort of size. I planted the tank heavily with several plants in the substrait as well as a huge amount of guppy grass, lowered the waterlevel to about a third of the tank (after substrait is taken into account), left the danio adults in for about a week, but can be done in as short as 2 or 3 days, before pulling them. Then a few days later noticed fry.

But the adults will almost always eat any fry small enough to fit in their mouth. Just a termanology thing, but female danio are heavy with eggs not pregnant.

NOTE: One reason for heavy planting is to keep fish not currently breeding from following the female, as she swims around dropping eggs, and eatting them before they reach bottom.

you can even put a tank of sorts together with less expense, perhaps.. just a storage box (those rubbermaid-like ones - we use them often as temp. tanks) with a small azoo filter or a sponge filter could provide you with a place for the fry for now.

I dunno what an azoo filter is like, but if it has an actual intake, you might want to put a sponge or something like that over the intake so that the fry don't get killed by the filter

good luck!

-- oops, here's the link for them. great little filters for a low price, even adjustable flow.

the netting from a fish net wrapped tight around the intake and held snug by a rubber band is a good way to cover the intake for fry but allow a lot of the debris through.

- this line of sponge filters of various size from them is also really good.

I know we use a lot of those rubbermaid storage bowl thingies as well as ... erm.. ice-bowls, which are about 3 gallons and sold real cheap at like wal-mart and target over near the kitchen supplies.

If you use something that small make sure to do daily water changes! Best of luck with the breeding.

yea, we've got a stack of those. they're handy for temp. tanks.

A place for the eggs to drop in should work well at the bottom of the tank; I have 9 Zebra Danios in one of my tanks (4 are glofish ones); and they are rarely ever at the bottom of the tank. Don't know about their breeding but I can't imagine Danios going to the bottom of the tank to try to squeeze through rocks to get to the eggs.
