Cherry Barbs Spawned.

Came home last night to find that there were eggs on my tank glass! I suspect its the cherry barbs that have been chasing one another alot recently in a show of courting!
The other suspects would be the bronze corys,however I have never had them spawn over the past year Ive had them so highly unlikely they have been at it!
So its the cherry barbs by the sounds of it. I have left them on the glass, while I was tempted to remove to them to a separate tank with a razor blade, however I decided to let nature takes its course on this occassion, however the eggs are still all on the glass some 24 hours later now! Most are still fine,one or two are turning white so they will become food at some stage.
I have some guppy fry already in the breeders net so Ive enough newbies to keep me going,although I imagine I will try to save them if they hatch at all.

Im actually hoping they are corys eggs!!! I love Corys.
I might just salavage a few of them tonight,Ill see what happens.
Is it likely now that given they have spawned once that they will now make it a regular event.? (Im at work so as soon as I get home,the eggs could actually be gone?!)
Gavin

How long before they hatch? 48 hours?

Thanks for that John,
I actually watched the tank last night for a good while and many of them hatched in front of my eyes! It was rather special to see it for the first time in the tank. What wasnt so special was how helpless they were when they are born and the neon and molly's ravishing them!
I decided not to try and save them this time around,I did some research on how to save them next time and will remove them from the tank next time around and hopefully raise a few of them.
I think Corys are fantastic.

It was amazing watching the eggs hatch,I could see them wriggling around inside of their eggs for a while and then they pop out, tiny tadpole like in appearance and swimming hard against a current,they drop to the bottom then and if they arent eaten on the way down they hit the gravel and bury away into it. (Presume they may indeed get wedged down there also).Anyhow likelihood of them surviving now is highly unlikely but next time I will be ready. Im hooked now on making them survive next time around!! Fantastic to watch I must admit,I decided to turn the lights off after a while at least to give them a chance to get to the bottom of the tank but with no prepared food source for them Id imagine they will not survive beyond the eating of the embyro stage.

Nonetheless, Im hoping now that my corys will make a regular event of it.
I didnt do a water change to trigger it either,only thing that may have effected them was I turned up the filter output, so hence more movement in the water and that may have prompted them to go about spawning. Otherwise its perfect!

Well, Ive changed the subject here to Cory Fry have breed. As per my tale last week, the eggs hatched and well they were either eaten or went to the gravel.
Today, I doing a water change, and low and behold the Cory fry are now free swimming but were rooted in the gravel. Many of them went into the dish that I was using after my water vacumn sucked them up during my clean. I then got a straw and slowly sucked the fish out of the dish and placed them into my quarantine tank. While I would of preferred to add them to the water from the tank they were born, it was needed to be done in a rush and again I wasnt exactly expecting cory fry in the tank when I started the clean!

So now, its a Sunday and I have them in the QT tank. They are tiny, dark but tiny. They remain silent and still on the bottom of the QT tank. (I did a 20% change on the QT Tank prior to adding them and also reduced the flow on the filter as well as adding some female black tights wrapped around the filter input so the fish wouldnt be sucked into the filter.I would of preffered an airstone and sponge but again I have what I have as they say.

Now some of the cory fry and swimming around now and then,the tank is complety bare but for the fry,heater and filter. For some reason there is also some dirt on the bottom of the tank that I have tried to remove as I know I need to keep it clean.
So what do I feed the cory fry now. I doubt the LFS up the road have brine shrimp so Im stuck needing to feed them something. Anyone able to help please.

All I have re food, is flake,some frozen,ground bloodworms(its actually just a red dust that none of my fish have ever eaten),and algae wafers,livebearer liquid fry no2 also.

Anyone able to offer me some advise please. I didnt get all the cory fry from the main tank,I would say there are about 12 fry in the QT tank now. Probably many more in the main tank burrowed amongst the gravel,will they survive?
I really need to know what food to get right now.

Managed to miss this thread before now.

Congrats on the cory spawning. You are now infected with coryitus, very hard to cure!

If the little lads survived the change to the QT tanks and remember at that stage they are very sensitive to a change in water parameters, you might manage to keep a few alive. If you have no brine shrimp or sny other live food to give them I suggest a good squeeze of a sponge for the main tank, there will be plenty in that to keep them going for a few days, you could also grind up between your fingers some flake food until it is just powder and put that in - but only add a tiny tiny tiny amount of it.

When corys spawn in a community tank, invariably one or two manage to survive, so they are hardly little things, but with a little help and the right conditions a batch of 150 or 200 from a healthy pair of bronze would not be unusual.

Good luck with them.

Thanks Darragh,
They are in the QT tank now,they appear fine still. I need to do a very small clean tomorrow of the bottom of the tank. Should I do 20% water changes every day still ?
I was also considering, would it be an idea to keep them in a hatching box in the main tank in future, I'll this lot in the QT.

Im heading away on Thursday until Sunday, will they be alright over this period if I gave a squeeze of the filter sponge from the main tank before I leave?

Only clean the tank of uneaten food, the mulm that occurs naturally will give them something to browse on and in small quantities will do them no harm.

They should be fine while you are away, if you have any java moss stick that in too, lots to eat in there if you are a cory fry.

A breeding trap in the main tank is a good idea for small numbers but if you want to raise a lot a small tank is better filled with water from the main tank. Here is a poor photo of about a half batch of C Schultzei, they are very similar to Bronze in breeding / qauntities etc.

PS. Those fry were only in the bowl for moving on to a bigger tank, they were about 10 days old. They were raised in a small show tank.

I found 2 or 3 dead fry today, have removed them and will do a partial water change tomorrow. The corys are beginning to move around alittle bit now but generally stay still on the bottom. Im hoping to have some microworms tomorrow courtesy of the v generous Lar.(Cardinal a big thank you).
So if I get them they will be hopefully in better form and will begin to thrive perhaps. I know its not yet a week old,but there are about 10 in the QT tank at the moment, I may do another partial water change on the main tank tomorrow and see if I find a few more.

Gavin

Gavin
They were posted to ya today...so you should have them soon. ...
Lar

Thanks again Lar.

Found a few more dead ones today,removed them and also removed some uneaten food. Im going to put some Java Moss in it this evening. I reckon there is about 5 or 6 fry in there at present.I may do a partial water change tomorrow of the other tank and if there are a few fry from there I will transfer across as well.

Gavin

The move from one tank to another at such a young age would have weakened them, so don't be surprised or put off if they die. You will get another batch in a couple of weeks or even sooner and next time you will be prepared.

The Corydoras napoensis I have had for nearly two years spawned for the first time today, but I was in Belfast and when I got home most of the eggs were eaten, I only got to say a few - that's the way it goes.

Daragh

Just 4 left there now, I got some microworms today from Lar and put them into the tank and they seemed to really get the corys moving! Im going to put one of the rocks from my other tank into the QT tonight as its full of Java Moss, so lots of eating there Id imagine while Im away.

Gavin

The rock and java moss will keep them going. Just remember that the amount of food required for four cory fry is absolutely tiny, overfeeding is much more likely to kill them than underfeeding. Fingers crossed for the last four.
