Cory Eggs

[§tudz]

Hi,

some of my bronze cory eggs hatched, I had four fry, and within 3 days they had all died?

Any ideas why?

The tank was fully cycled, I did a 10% water change every day, with water that had been dechlorinated and left to stand for 24hrs, I added interpet liquifry. I added meth' blue to the tank when adding the eggs.

Temp was 26*C water was clean, there were little infusoria swimming around in the tank waiting to be eaten.



I've now emptied the tank and refilled and I have added some triops mixture, so going to hatch some triops, they only last a few months , then I'll try and hatch some more cories but in the mean time any help, as to why the fry would have died?

Cut the temp back to 24dC and don't feed them for three to four days. Let the yokesack disapear then feed them. Lower the water level down to around 6" to make it easier for them to survive. Watch out though when you put all the eggs in for they might all survive and then you'll have a nightmare of a problem with water changes.

Thanks, the water level was around 10" so I'll drop the level and the temp next time. the triops I'm going to breed only last a month, and then I'll dry the substrate out and package it away as they last for 30yrs+ out of water.

/me crosses his fingers for the cory eggs next time

Hi §tudz

I'm sorry that you lost your cory fry and hope you have more success next time.

Your water was a bit warm for them, but I think the real problem was with the LiquiFry. You have to use it very sparingly. If there was anything swimming in the water, you used too much.

Perhaps next time you might want to start a microworm culture to feed them. I like them because it's easy to remove them when doing water changes and I like to keep my cory fry in clean tanks. I seem to have less loss that way.

I keep the water level at about an inch from the top and find that they do well. Their natural habitat is in rivers so they don't need shallow water.

Good luck with the triops. I had to look them up to see what they were and they do look very interesting.

lol, interesting? a way of saying ugly scary little things

I read on a web site that a clean bottom tank, would produce a film of bacteria which attack and kill the fry?

Thanks,

as long as you do regular water changes & removed any uneaten foods they will be fine in a bare bottom tank, i would listen to the advice given by inchworm as she has had many cory fry that she raises regular like this. in fact it is inchworm that has helped a lot of us on here with our cory fry, from getting them to spawn to them being grown up
