Peppered Cory Eggs

[lilacamy931]

Aw sounds like you are doing an absolute fab job well done! The only two I have managed to keep alive so far are the ones in a gigantic koi sized net which clean regularly. Unsure how others have coped with the sand, believe just stir things up and suck out as much as possible...

Congrats on the fry so far

I would try to get has much out as you can,fry can die quite quickly from bacterial infection from uneaten food etc,like amy says,give your sand a stir a bit at a time and suck out the crud that rises,

I do this every day on waterchanges,i lift the moss balls also,if you leave this part till last move the moss ball over the fry will shoot out and hide back under it.if you accidently suck one up,just pop it back in the tank again.

Thought I was seeing things for a while, but the tiny white specs that I noticed a few days ago on the aquarium glass (and thought nothing of at the time) are actually alive. They look like some kind of mite and keep darting around across the glass. We're talking really small here, maybe 0.5 to 1mm max - pinhead kind of size. Any ideas?

It may be planaria,caused by overfeeding in the fry tank,and or when ammonia levels are up...

My peppered cories have bred lately also, and like you I got a load of eggs, but only a few survived. Got about 60, and 6 survived
They were laid 2nd Jan, and today i added the two biggest ones back into my community tank. They are such miniatures for the adults lol.
The female spawned again the other day, so Im waitin to see if I get anymore

Hi, I just googled planaria and I don't think that's what I have from the images/descriptions I came across. More like mites/fleas than worms. You're probably right about the overfeeding though, as I'm finding it difficult to judge how much bbs to put in the tank. Sometimes I add a pinch (from a net after rinsing them to get the salt water off) and can't see many in the water so I add a second pinch, but when I put the fry tank light on I see the water full of them - way too many for the fry to get through!

But, what I've been doing to counter this is twice daily 50% water changes and hoovering of the sand with some air tubing. I'm pretty sure this regime is getting rid of most of the bbs before they die and start to decompose.

Did a proper head count today. 14 fry, most about 1cm long and some starting to explore the height of the tank now, instead of just travelling across the bottom. Was just watching one earlier and observed something quite odd. The fry must have been full of energy because it suddenly shot up from the sand and started exploring the middle/top areas, at a pretty rapid pace. But all of a sudden it just stopped in it's tracks, remained stationary for 2 or 3 secs and then fell slowly to the bottom. It didn't try and swim/move at all - just dropped. I honestly thought it was dead - a heart attack or the fish equivalent bought on by the sudden exertion - but then after a minute or two it suddenly scurried away. Some pretty interesting behaviour to observe

Water fleas? I had these in a tank on the window unsure if harmful or not, live food for them?

Quick update - all fry doing well, apart from one that I found lying dead on the sand when I returned from work today. I've got no idea what happened, but the others all look active, so I presume are healthy. I'm still feeding a combo of live baby brine shrimp, live microworms and First Bites. Should I be trying any other types of food now? Not to sure at what age to maybe start introducing frozen food such as bloodworm (the smaller ones) or daphnia, etc. The biggest fry is now approaching approx. 2cm, though most are somewhere between 1 and 1.5cm.

They seem to be doing well,

You could try grated frozen bloodworm etc,if you grate it before it defrosts,you can get tiny slithers for their wee mouths.

Ah, okay. I'll buy a pack of bloodworm tomorrow, as the ones I picked up last time are the larger variety. Thanks for the tip.

Hi Guys, the fry are now 23 days old. Started with 14, lost one a couple of weeks ago and found another dead today, so 12 remaining. Just wondered at what stage their chances of survival increase? I'm guessing at some point soon it must be more of a surprise to find one dead rather than something you just expect?

Still doing daily water changes to keep keep the nitrite away, but was thinking of boosting the biological filtration by adding in a small internal filter (Eheim Aquaball) to supplement the foam filter that I've had in the tank from the start. You think that would be okay or would there still be a danger of the fry getting sucked in to it? I'm guessing it would work out okay, but you guys have done this before so would prefer to check with you first!

You're doing fab,i tend to lose mine around 2-3 wks old,not for the want of trying,i reckon once they go past the 4-5 wk stage they get a better chance of growing up..

I have an eheim aquaball but i found this too powerful and kicked the water and fry around too much,depends how big your tank is,i presently have a mini elite filter,this is adjustable,and i have been turning it up slowly has the fry grow,and stats have been spot on.
If you do use it just make sure you put tights over the intake to stop the fry being sucked up.

Hi and thanks for the reply. It's an Aquaball 60 (the second smallest) with a quoted flow rate of 480 lph and is designed for a 30-60L tank. My 'fry tank' is a 35L Arcadia Arc. I think I'll leave it another couple of weeks and then add it with the flow turned right down. It's currently running inside my 5ft tank so the extra 2 weeks will allow more beneficial bacteria to develop in it.

Btw, when would you say is the right time to move the fry into my community tank with their parents and the other inhabitants?

 

[Harlequins]

Well funny you should say that but i've just added 2x 9 wk old juvi trilineatus to my main tank,i haven't got no threats in there that would attack or eat them intentionally.

But i think its recommended that they're probably better in the fry tank,whilst you are doing daily water changes,these help to promote growth in young fry.
But i have a mixture of different ages,and i was worried that these juvi's would eat the newly hatched fry which has been known to happen.
