Swimming baby!

Looking good, i had 18 eggs and the pleco's saw 12 off last night, what breeder box do you suggest from amazon as i'm with them please.

I can't help there I'm afraid, most seem to be designed for livebearer fry, which are much larger than newly hatched cories. I used the frame from a cheap breeder box and pulled a pair of extra large tights over it, so that the holes would be tiny enough that cory fry couldn't escape.

Congrats on the eggs!

I think i'm going to have to hunt then because i think by tonight the rest will be gone, my cories breed weekly and my emerald male keeps trying with the female but nothing as happened.

I went mad a few weeks back purchased 6 young panda cories and only 2 survived the rest went in 2 days and it cost nearly £45 for them as they're hard to get here.

I'm sorry, that's awful. Panda's are pretty weak now, a lot of people have had bad experiences with losses with panda cories.

For now, you could clean an old ice cream tub, margarine tub, takeout container, clip that to the side of the tank, and put an airstone in it, put the eggs in that. That's what I did for the first day.

What i did the first time was get a tub and put 11 eggs in it that was fertile and removed several unfertile ones and my husband pushed holes through the side and we strapped it into the water as fresh water was going through in my main tanks and 3 lots of oxygen going in there and they got bigger the eggs did and on the 4th day they looked lifeless so i removed them.

I've had no luck with pandas, either. I got six white ones, ended up with one. It now lives with my green laser corys.

I think it's a total shame on all of us who purchase the little beauties, well i've got my 2 with 10 cories and they soon get stuck in with the food.

I'm a lot more cautious about buying corydoras that are common in the hobby and overbred commercially. I also had terrible luck with C. trilineatus, which all keeled over one by one over a period of months. I've done much better with either wild caught or marginally less common species.

That said, I've had the black ones for about eighteen months now, and I bought them at Pets at Home! C. schulzei is really just a color morph of C. aeneus, so it's anything but rare. I'm 95% sure that they're the parents of the fry that have just hatched.

My son in law as the black ones and had his from Pets at home and his do well but he's ventured into albino's now besides bronze seeing mine and they're doing well.
What i do though since buying the first time as i purchased 2 bronze and one died over night, i was told to put them in my water in their bag and after 10mins add some of my tank water to the bag to help ease the toxin they can release through stress and leave them another 10 minutes and put them in and had good success with them all, it's only the pandas they went bad on me.

Well, found 3 dead Cory fry when cleaning this evening. This part, I’m use to as I know some won’t develop all the way. Still makes me sad. On a positive note, the cherry barb fry are swimming fast now and I hope they will be safe. Hope the moss gets here soon. Per NCaquatics, I added one nice size ramshorn snail to help clean the bottom of the tank. He’s one happy snail.

Ah man, I like ready brek! LOL. Will start a couple of new cultures tonight, might put one in the fridge, read something about slowing them down but keeping the alive? but might not, because it turns my stomach a bit already when they're shut away in the cupboard, really don't want them in my fridge! Maybe I'll just stick to starting a new cupboard culture every few days.

Culturing them is easier than I imagined though! For anyone wanting to try a live food culture but they're nervous about it, I can recommend starting with microworms. So easy! And cheap. Bit of supermarket brand porridge, some yeast, and some empty takeaway containers, and my starter culture cost less than £4. Cory fry seem to like them a lot I think! They wriggle around when I add them anyway, and the guppies go mad for them too.


What a beauty! Never would have thought of a shire/TB, but it's a great mix! She doesn't look her age at all, she's gorgeous, thanks for sharing!

Did a head count today after cleaning their tub and before adding sand, since they started hatching seven days ago! Some are a week old already I can't be totally sure, but think I have 12, however one of those looks like it's dying. The others look bigger and wriggle around more purposefully, but I thought this one was dead at first, but it moved a little when I sucked it up and put it on a plate in some water. Think I will lose that one by tomorrow.

Sad, but I'm trying to take it on the chin a bit more, that sometimes it's going to happen. Bit alarmed that no one else seems to be losing any, and I've lost three already, with a fourth looking like it's on its way out. I'm keeping their tub clean, water is pristine with water changes every other day and their breeder net is in 12.5 gallons of water, feeding 2-3 times a day, airstone underneath their box... I don't know what, if anything, I'm doing wrong, when everyone else is succeeding.

Have some photos incoming.

I lost 3 today.

I can’t get over how fast they are. You guys may not see it yet since yours are in breeder box’s. These guys zoom all over the tank. So cute. How long do you guys plan to keep them in boxes? I’ve always heard it makes them stronger and grow faster if they get plenty of exercise. Maybe that’s just for goldies.

Yeah, that's how I introduce any new fish to a tank. Float them in the bag, and add tank water every ten minutes over a period of about forty minutes.

My pandas were in my 240L tank, and I was concerned that the raphael catfish bore some responsibility for the untimely demise of a few of them, as they were small juveniles. After losing four (not entirely to raphaels....one I found dead, but uninjured, one started swimming in spirals so I euthanised it, and two just disappeared), I shifted the remaining two to my 125L tank, which didn't house anything remotely predatory. That tank stays at 27,C which isn't ideal for panda corys, but I had a new 110L tank, and I knew they could go there once it was fully established. Interestingly, one didn't grow at all. There must have been something underlying, so maybe I'd unfairly blamed the raphaels. Not everything is their fault. That fish died during a white spot outbreak. Once fishy Covid seemed cured, I moved the remaining panda into the 110L with its green laser friends.

Back to the fry.... some of mine don't look like they're still attached to egg sacks and they were zipping around. They have an Indian almond leaf and some leaves from the main tank.

I'm not sure, 2-3 weeks I think, then probably let them loose in the main 12.5 gallon grow out. Once they're big enough for the rapidly growing guppy fry not to eat them, and the adult cories have been moved out.

I'm torn, because I kinda want to spawn the adult cories one more time before moving them to the 57 gallon, because it'll be my last chance to spawn them. If they spawn in the big community tank, eggs won't stand a chance. So it might be a bit longer, not sure at all yet. Need to do more research. Don't want to stunt them, don't want them to have a hard time finding food too early either, ya know?

I'm sorry you lost some too, it does happen, as you know.
