C.30 looks like a high possibility. Unfortunately the supplier who brought them in does not know where they came from. And yeah u're right about that, they look fantastic!!!

Just grabbed a trio of them although not sure what they are. Some ID them as corydoras burgessi sp while some said it could be corydoras bicolor.
Any ID of these guys?

These guys turning out to be aeneus venez-orange Will try get some pix of them now (6 weeks old)

Cool movie!!! I never got to see my cories in action though

Thanks Ian!! Will try to get a picture of them when they're 5 or 6 weeks old. Right not, they're already feeding on tubifex and the maximum size of the fry is 12-14mm

Think the fries are too early for a guess huh?

All right finally managed to sneak some time out to take some pixs. Below are the fries. Majority of them are 10mm big now and starting to take tubifex worms

Thanks Ian! Arrrggggghhhh!!! I really thot I could have more hastatus. Oh well, at least now my list is shortened :wink: :wink: Do you mean in another one months' time (when they're 7 weeks old)? Or you mean when they're one month old (in one week's time)? 6 schwartzi 5 similis 4 arcuatus 3 ambiacus ...

Just thought that I might as well take out those species which are unlikely suspects :) So below the list of the likely culprits. Gonna take a pix in another week when they're about 1 month old 8) :P 6 schwartzi 5 similis 4 arcuatus 3 ambiacus 3 loxozonus 4 atropersonatus 1 aeneus + 4 albino-aeneus ...

at 15 days of age it is almost impossible to pinpoint who the parents are of these fry.. at this stage 90% of the fry look very similar to each other. i would give it 2 or 3 more weeks before they start growing into their adult colors.. anything right now would just be a guess.. madattiver, thanks ...

Found 2 batch of eggs with an estimated count of 120+ eggs. Eggs were 1 to 1.2mm big and whitish in colour. Hatch rate was about 90%.

The cories that were in the tank with the eggs: 6 schwartzi 5 similis 1 duplicareus 1 melini 2 leucomelas 4 arcuatus 3 ambiacus 1 metae 3 loxozonus 4 atropersonatus 1 aeneus 4 albino-aeneus 1 sterbai 5 venezuelanus-orange 20+ hastatus 2 julii 1 simulatus 1 gossei 3 davidsandsi 4 caudimaculatus 3 ...

Taking a long shot but since I gonna return them to the parents sooner or later, I might as well try ID see who 'did' i while I was not around

Here a pix of a 15 day old fry. Any idea which species it could be?

Duplicareus

I guessed it is a c.arcuatus but it sure does not look like one cos I've got 6 juvenile arcuatus with me. The dorsal fin is also black if you noticed. Do juvenile arcuatus have a lateral line on the body???

Done

caught this in a tank of arcuatus ... but its different ... anyone knows?

Yup I'm having the same thoughts as Dennnis. Any comments anyone?

Thanks Ian for the prompt reply! It is precisely the agassizii and ambiacus that is giving me the headache :D I've taken a look at the pictures and could not figure out the differences :? The only diff I see of the 3 is that c.lamberti has only a black blotch at the tip of the dorsal fin whereas the ...

Over here at Singapore, we have a few batches of cories that looks very similiar to each other. They look very much like agassazii, ambiacus or even lamberti? Can anyone give a definite guide on how to differentiate them? I will try to post pictures later
