The ones on the picture (not circeled) are not blochi blochi, but C102 or another "leopardus"-looking fish.

The ones circeled (at least one of them , the other one turns the back towards us, so difficult to tell) is not C. lamberti, but some agassizii-looking fish.

This is one of Hans evers ...

I'd say C125.

It depends on a lot of things.

My atropersnoatus leave the eggs alone but eat the fry. Other hobbyists report that their atropersonatus eat the eggs.

My C120 left the fry alone in my tank, but after giving them to a friend, the very same fish suddenly eat the fry.

It's not something that's easy ...

Both napoensis (might be C126. difficult to tell on young fish).

Corydoras CW9, aka "green stripe". Natural form, no hybridisation involved.

Looks like C133. Nice fish. Last time I saw them in a shop they were £30.

I'm pretty shure Joachim Knaack bred them and Hans Georg Evers could well have done it too...I don't know any more than that I am afraid.

Should. Never seen them in any shop.

Have a look at CW002.

Well...theres's C10 and C80. Maybe C103 as well...

There are probably more of these spotted ones that come unnoticed as contaminants. All difficult to tell apart.

It is defiantely neither osteocarus or ornatus.

I think the snout is too long for the species Richard mentions. I would lean more towards delphax allthough the pattern is a bit large-spotted for those also. It could be one of the manu C-numbers with a pattern like this. A catch-location would have ...

It is CW44, often imported ad C. elegans.

They can be very dark or very green, depending on mood etc.

This just happens.

I have mostly experinced it with groups moved to another tank or with groups where specimens have died or new ones added. Funnily enough, the same things can trigger a group into spawning.

I'd say yes.

There's some loretoensis over it, but still a bit different. The dorsal marking looks too large. Some loretoensis can have black first fin rays, but not this much. not that I've seen anyway.

Looks like young C. lamberti to me. From around Iquitos?

C91

This looks completely new!

...I have never seen this before.

Loads!

Corydoras carlae, C7, lingopinnis, CW22, undulatus, Scleromystax spp. (other than the barbatus you mention), some Ancistrus species and Hisonotus aky etc.

Plenty to choose from, but many are not very easy to get your hands on from commercial sources.

@rmc: I happen to be lucky to know a few people in the UK and Germany who do/did quite a good variety of Aspidoras species. I forgot A. depinnai in my list BTW :)

Usually they are vary hard to come by. The only commercially imported species you will find here is taurus and "araguaia" wich seems to ...

Currently I only keep A. poecilus and CW52, but have kept and bred others over the years; C35, C118, C119, C125, eurycephalus, taurus and cf. rochai.

All but eurycephalus and C35 I found very easy. 119 I never got to breeding...they were very agressive to eachother.

They are C. axelrodi.

Well done :) it is a very nice species.

My own group (1 male, 4 females) produce a new baych every time the male is in the breeding tank for more than a day...I have somewhere around 200 youngsters from newly hatched to 5-6 cm. so I am keeping the male seperate for now :)

Unfortunately everyone ...

Thanks Racoll.

I thought L183 too, but I was thinking someone might have imported some and could give me a pionter to what they had as L59 from there. I had been through all the Rio Negro Ancistrus but couldn't find any leads.

I have seen a list from Brazil with L59 that is supposed to have been caught in Rio Negro. As far as I know this fish is not a Rio Negro fish so what can it be?

Ah ok, a good place

Just out of couriosity; who is this Danish importer?

I've followed this thread on and off for some time and had a few large spotted C. Perugia for some years. All females but laying eggs!

In the hope to get some males I ordered some from a source in Germany and got 6 nice males and females...small spotted! So I keep the seperate from my large spotted ...

It is fairly common in Corydoras.

Hastatus and pygmaeus are in the same lineage so there would probably be a possobility. Habsosus however is in a completely different leneage with C91 and other roundsnouted species and I wouldn't think they would crossbreed with the other two species.
