Omg Cory Eggs!

[snazy]

Forgot to say, make sure if you are not already doing it to mix the food with a little bit of tank water and then pour it right down the bottom. I use a syringe.

Three of them died yesterday and I have no idea why

Just one left now. He does seem to have a much bigger belly than the others did, so maybe he was just getting all of the food and the others didn't.

I started out with a very small smattering of sand on the bottom, but as I did water changes the sand ended up getting pushed around to just one area. I've added some more now to hopefully stop that happening and I will make an effort to move it back if the bottom ends up exposed anywhere.

I had started feeding them more often because I saw there was never any noticeable leftovers. Will do a bit more now though.

The filter has been a bit of a pain. I'd get it rippling the water and I'd come back a few hours later and it wasn't doing it any more. I've turned the spraybar upside down now and lifted it above the surface a bit more. Seems to be working great now.

I've also thrown a few java fern plantlets in that I got out of tidying up my main tank.

Will try and get a photo of my one remaining one, though I need to charge my camera first!

Update: One remaining baby still alive. Very recognisable as a cory now. Looks the same as the adults now, just tiny. Not too tiny though. Not far off from being big enough to put in the main tank now.

Seen a couple of my cardinals swimming around with cory eggs in their mouths, though I've not seen them spawning.

Update: Came home from work last night to fins my cories had been at it again and eggs in my tank! I almost didn't save them but I'd feel bad if I didn't, especially since I've still got a fry tank running from the last lot. Rescued seven eggs (there were also the remains of a few more in my tank that my fish got to before I did). Six of them are good this morning.

I've got them in the bottom of a coke bottle and suckered it to the side of my fry tank underneath the spray bar, so the water from the filter goes into the bottle before overflowing back into the tank.

One remaining fry from my previous batch still going strong! He's probably big enough now to not get eaten in my main tank, but he'd probably get sucked up by the filter and I have bad experience of putting things over the intake.

Three baby cories found this morning. They are tiny! I'd forgotten just how small they are when they're born. They're in with my other baby who is approaching 2cm now. I'm worried they're going to get eaten. Is that a reasonable worry or am I being paranoid?

 

[snazy]

Well my "babies" which are quite big now are not eating the tiny cherry shrimp which actually eat alongside them so I wouldn't think newborn corys would get eaten either. I also put some of my oldest ones with newborns and they didn't eat them either. At 2 cm the old guy could still be enjoying powdered food really quite well. Corys don't seem to be fry eaters but rather accidental fry eaters but at that age I doubt it.

Five more eggs tonight!

I was lucky enough to have the original baby stop right by the edge of the tank and I had a ruler to hand. He measures 22mm!

I've lost all three of the fry that were born last week. So annoying as I can't see what I'm doing wrong. The original little baby is still doing fine. Considering putting him in my main tank soon as I think he's too big to get eaten now (my biggest fish is a male German Blue Ram). Just need to get some netting as I dont trust him with my Fluval 305 filter; the intake is pretty big.

My cory babies that showed up in my tank were first seen by me when they are about that size. I worry about them a bit, but mine would come out of a cave in my tank, work around for some food, and then scurry back under cover. They never get anywhere near my intakes. Do you have any hiding spots like caves in your tank that would be just big enough for the cory babies, but not big enough for the bigger fish?

 

[CezzaXV]

I've put the baby in the main tank with the rest of my fish now. He's been in there a few days and seems to be doing fine. He shoals with the adults and everything!

 

[eaglesaquarium]

Congrats!

 

[snazy]

Lovely. He should be fine. I remember I put my first surviving cory when he was 5-6 weeks old and he grew up just fine with the adults.

 

[CezzaXV]

Just found some more cory eggs in my tank! Having only just shut down my fry tank, I think I'm just going to leave them where they are and what will happen will happen.

 

[eaglesaquarium]

How much cover do you have in the tank? My cory babies survived, I believe because of the "caves" in my tank. I have some slate set-up as a sort of a teepee and dug out deeper in the sand by the fish... and a large piece of driftwood that my BN pleco has dug the sand out from under... and that's the two spots I've seen the babies moving around. I've seen the smallest baby yet a few days ago.

I also have live plants which provides food and cover as well.

 

[CezzaXV]

I've got a fair few plants, along with some homemade coconut caves that are too small for most of my fish to get inside.

The eggs that were on the tank walls have been eaten as I expected they would be, but it's more than possible there are more eggs hidden on the underside of leaves that my fish might not notice.
