cheers flash

Yes, you can remove them. Check out the "Sticky" at the top of this forum on how to care for the eggs/babies.

I think the suggestion I've seem is to roll them onto a razor-blade or something similar. They are quite sticky...

HI Flash,
Congrats on your haraldschultzi spawning.

In my experience with other Cory sp., yes you can seperate the eggs. After a few hours they become quite resilient and can be 'handled' readily. Before this the egg membrane hasn't hardened and is liable to pop.

Try to avoid contact with the air - tease them into a cup or similar - can be tricky 'cause they're likely to be v. sticky. You could put a couple of spawning mops in the communituy tank for future spawnings.

I usually have a seperate tank on standby, with the same tank water as the parents and a biofoam or similar plus an airstone for extra circulation. I don't use substrate in the rearing tank. A few drops of methylene blue will reduce light to the tank and help to inhibit fungal growth.

Good luck - may be worth considering a seperate breeding tank for your cory's in the future.

Cheers,
Mark.

Great Job. C. haraldschultzi is a difficult Cory to spawn. Please try to document all of the water parameters.

Hi all
by the time i got home from work all the haraldshultzi eggs had gone.so this weekend i will set up a tank just for the adults and hope they dont go" off the boil" as for the water
parameters my main tank is full of bogwood and rocks and plants .and my sturasoma are almost always sat on eggs (3 pairs)so i can only do a water change every few weeks.the bottom is coverd in leaves so the nitrate and nitrite are probably very high.

I surely hope that you don't have any level of nitrite - that's a sign that your beneficial bacteria aren't working as they should. Sure, you'd get high nitrate by not changing the water, but you shouldn't get high nitrite unless your "breakdown ammonia bacteria" has died. And that's probably not the case if your sturisoma are breeding...

hi all
the truth is mats that im an old school aqarist i overstock ,overplant and overfeed i dont even own a test kit
if any fish die its either old age or some stupid mistake that i made. yet in my 100 gall tanks(x2)i have emperor tetras, black neons ,angels,rhinoloricaria,and sturasoma all spawn regularly .im in the process of building my first true fish house .not just the spare room.so mabye i should start and learn some of the "science" of fishkeeping

If it ain't broke, don't try to fix it

I've not tested a mature tank for nitrite unless I thought there was a problem - and even then, I didn't find any...

Test kits won't keep your fish alive unless you test very often - but looking at the fish can tell you if they are OK or not. However, a test-kit can help you tell WHAT has (or hasn't) gone wrong wrong with a tank if the fish is looking poorly. But better than any other indicator is the fish itself - happy fish are a good indicator that all is fine...
