Just below C-150...147 i think...not shure though.

The "poop" will lay on top of the sand and therefore it's easier to remove.

I use rainwater...never had any problems with using this. Don't you mean the other way around regarding sexes?...4 male to 2 female? Usually more males than females are recommended, and I usually group my fish this way too (more males than females). I think the dividing of the tank into 2 or 3 sectu...

I have seperate tanks for breeding Corydoras, but I guess it's close to the same as dividing larger tanks. I use HMF-filters i each tank. You could also use a central filter, but i think a large airpump with HMF-filters are perfect. With the central filter you could spread diseases between the tanks...

I would use sand instead of gravel. Some pieces of wood and big clums of javamoss, javafern, or other plants they can hide/lay eggs in if you are so lucky. Temps around 23 degrees celcius would be ok. The light is more important to the plants than to the Corys in my opinion. Corydoras panda would be...

I've never had any problems with hydra, but I think I've read in an older tread that Ian F. uses a Blue Gourami as a "biological weapon" against these...

Had some excactly like that a year ago...never decided on wether it was C. kanei og C. atropersonatus.

Very nice indeed...I've been thinking of getting some Otocinclus and try to breed them. It is possible, although it seems rather coincidential when it happens. I've been breeding various Corydoras and Parotocinclus jumbo for a while...Otociclus are said to be somewhat similar (i.e. cold water change...

Nothing wrong with that plan I guess...

Unfortunately my eggs fungused...hmm. Well, if thay laid eggs once, they can do it again

They produced 2 eggs saturday afternoon. Hadn't noticed any breedng activity at all, but suddently there were 2 eggs in the java moss...temp. 22 degrees celcius, 50% waterchange once a week with rainwater and a power filter to make strong corrent, in case anyone is interested in the details... Any l...

I'll go for C. habrosus...

I would think it is a defect swim bladder. I don't think you can do anything about it. If it were my fish, I'd probably killed it and bought a new one.

You could remove the eggs to another tank or container with water from the main tank. If you sieve the water though some cloth or something, you might avoid transferring hydra to the tank. Or remove the fish from the tank and treat the water with methylene blue. I don't know if the methylene blue ki...

Yep, LDA-025 are funny little buggers. I have a breeding pair and a billion fry...the fry tank is alive

Hello Ian, sorry I didn't think about their age. They are at least 4 years old. I have 10 fish in the group (4 females I think).

Could it be they are too young?

BTW, known water parameters:

Temp. 24 degrees celcius, pH around 6,5. I use rain water.

Hi all, my C. davidsandsi are spawning a coulpe of times each week...the eggs are fertile, because they don't fungus, and I've had a coulpe of fry swimming around. The problem is, that even though there are 20-30 eggs every time and none og the fungus, I get no fry. I've tried everything, it seems. ...

They are looking good, besides some fungus on the tail of one of them...they refuse to eat tablet foods...only frozen foods are accepted. Guess I'll have to go out and get some live foods too...

Best regards,

...hmmm....I think C. arcuatus is a tough one to start with. They are supposed to be hard to breed, but I've never tried this one myself. If i were you, I'd try some of the "easier" species first, like C. panda, C. paleatus or others. Look through this forum...there are plenty of treads ab...

Thank you, Mad Scientist... They seems ok with their surrounding. I am hoping to breed them, but not much info available on this species...

Best regards,

I think it depends a lot on the species...

Fortunately I have an agreement with a store that mostly sells South American fish. The owner would rather buy Danish-bred fish than wild caught or asian/easter european bred. The survival-rate is better than wild caught and the quality is better than asian and eastern european mostly are. So that's...

Yes, it's good to know you're doing it right ...but at some point one runs out of room for more fry...

Hello all... A good week ago I asked for info on C. albolineatus, wich I thought I'd buy yesterday. Unfortunately (for my wallet) they were out of stock. But instead I ended up buying 8 C. pantanalensis, wich I've been searching for for some time now. They are big fish, between 7 and 8,5 centimeters...

Hmm...didn't get the C. albolineatus...out of stock...BUT...there was 8 C. pantanalensis swimming around...couldn't help it...had to get em

Ok, thank you BronzeFry...I also think they'll stop for a while at some point. Just surpises me that the females can procuce so many eggs. I've got 10 fish, and i think the 3 og them are female, possibly 4.

Hi all, just a little question... How common is it for cories to spawn sevear days in a row? I've experienced my sterbai, pandas and pymaeus to spawn two days i a row, but my davidsansi are going on and on and on...for the past two weeks it's only been two days where the DIDN'T spawn! ...is this com...

Yep...my fish looks like that. They are around 3-4 cm. also.

Best regards,

Hmm...they don't really look like my C. venezuelanus. Mine has a lot more colour. Dark shiny green spot with lots of rusty/orange around it. I'm not saying yours aren't C. venezuelanus though. I think the colours are just a little pale. Have you bought them recently? Could be that they were't quite ...
