Harlequin Rasbora spawn… help needed ?

Woke up this morning to find about 80+ eggs deposited on several a/sword leaves and presume it must be the harlequins, which I gather spawn on large leaves, but don’t spawn easily, lol. They spawned in front of the outlet for the power head, so no doubt like to choose a place with strong water movement as I gather in the wild they spawn in strong flowing streams.

It’s a temporary 450lt housing tank, so I will have to remove the eggs or wrigglers rather than the parents and all the other fish. I see they hatch within 18 to 24 hours, yikes, so I need some help or advice fast? I've set up another 40lt tank which I will full with the same water. For food I understand I need to get infusoria going, so would welcome advice from the beta breeding folk as to how best to quickly do this or any other advice and tips as I have no experience with breeding rasboras..

 

Cool and congrats.Wish I could give advise.
As for infusoria I heard that the Banana Peel option works best.

 

@Trevor Pleco - Yup - banana peel works - boil some,take that water and introduce some filter mulm/pond water/liquidised spinach,letuce/old green algea ridden water from your birdbath etc...leave in sunny spot,wait 5 - 10 days and you got a nice culture....so not an option here...

Hate doing it,but these surprise spawnings leave me grabbing for Liquifry no2 for egglayers every time....40l tank it wont be to expensive and you'll have em on your famed microworm culture in no time... Start hatchin BBS as well - works a treat once they over the 1st 3 - 5 days of free swimming and Liquifry...

 

Congrats. What other fish are there in the tank?

 

Thanks for the congrats and advice, but lets hope first that the eggs or some of them are fertile, as within the last hour or so I see about 30% have gone white, thought I best keep them in the tank as long as possible before making the tanser..and if and when we reach the wriggler stage.

Will eat a few bananas in the mean time, thanks.

cardinals and rummynose all waiting to pounce and some corries and bristlenose, so almost certain it's the harlequins, as they are still doing their display/foreplay thing close to the plants, have about eight in the tank.

Presumably they will not starve within the first four or five days and can survive on the yolk sac and while waiting for an infusoria culture, also just popped into my LFS to make sure they have 'fresh' Liquifry 2 in stock which they do, won't buy untill I need it, as that was a bad omen in the past.... the idiosyncracies of the crazy aquarist !

 

Cool, my corys spawned yesterday and I thought they looked like cory spawn. Hope they make it!

 

I thought the Cory family were more egg 'scatterers' not leaf depositers, but have no experience with either ?,

 

I know that my eggs were cory because I have had a batch hatch, the new ones were laid on the glass next to my thermometer.
Only time (or another member) will tell.

 

Those look like Cory eggs to me, they lay batches like these on powerheads, filters, aquarium glass, large leaves etc. but if you saw the harlequins dancing/displaying then it could be them. High percentages of fungused eggs are also common with cory eggs.

 

OK thanks, won't rule this option out, but the eggs were laid at the top 10% of the water column...

Have six albino cory in the tank amd two pandas, so could well be. Having said that this was the first time I have seen the Harlequins doing their display stuff, fins all out stretched and siding up to eachother.

Perhaps they are simply coreyquins !

 

Update..., no sign of any wrigglers yet, have about thirty five eggs that still look good. As I understand harlequins hatch within 24 hours, it seems it must be the albino corries, surely not the pandas... ! Interesting they have chosen to spawn in a place they seldom venture in the tank, an inch below the surface, but it must have been the introduction last week of the powerhead on that side of the tank that stimulated things. OK, any advice on first food for the fry -- brine shrimp, microwroms, liquifry ?

 

They also look like Cory eggs to me. Mine put eggs on the glass about once a month, but I've got too many other fish in the tank that are hunters, so I've never seen them go past the stage where it looks like there's something growing in the egg. They're always eaten up within 48 hours

 

I have had bronze cory eggs a few times and those look the same. Cory eggs usually take about 3 days to hatch and then another 2-3 days before the fry need feeding because they have yolk sacks. They are very small, about the same size as newly hatched danios(2-3mm), so i would suggest a bare bottom tank or some fine sand. Try putting an airstone by the eggs so there is more water movement which will prevent fungus or use methylene blue. Also i've heard that the eggs shouldn't be removed from the water. The viable eggs usually turn brown and if you see some with fungus on, remove them because the fungus will probably spread to the others. As for food, i have never used anything besides liquifry. Small daily water changes are also required.
Hope this helps and good luck

After liquifry, use microworms. They are supposed to be the best food for young corys.
