Re: Corydoras ln8sc4 identification

I am curious as to why one of them might have developed such long pelvic fins, I've never seen that before. Could it be a form of sexual dimorphism, regional variation or just random? Unfortunately their origin cannot be determined as they came from an online seller selling them as C. punctatus - an...

Re: About filtration

Interesting thread, I have been running my Corydoras tanks "unfiltered" and have not experienced or noticed any adverse effects. Both have strong circulation via large uplift tubes with strong air-stones and a reasonable amount of plants. The tanks are heavily stocked and do get regular la...

Re: Corydoras Eques setup

Lovely tank, the fish are looking very happy.
Are they emperor tetras you have in there with them?

Nice! Any plans for more? Because, you know, Corys are best kept in groups! ;) :D

Re: Corydoras ln8sc4 identification

Here are some more recent photos of the fish in question, taken since they have settled in and grown a little. Three of the five have very similar patterning, one has stronger colouration and one has significantly longer pelvic fins. Z62_6841.JPG Z62_6844.JPG Z62_6854.JPG Z62_6879.JPG Z62_7001.JPG

Re: Corydoras (ln5) id

Thank you. I was leaning towards CW105 on a superficial appearance but the stripe from eye to dorsal seems to rule them out. A shame there are not more photos of CW029 but one other similarity it has to my fish is the small spot at the caudal end of the central stripe.
Cheers,
Andrew

Re: Corydoras(ln9) sp. (Cw063)?

That's interesting about the association with a 'mimic' species. I will see what I can find out about their origin next time I visit the shop, probably in the new year.

Corydoras (ln5) id

I thought these might be C. bilineatus but apparently that species is not commonly encountered in the pet trade, I am wondering if they might be Cw029 or Cw105?

Corydoras(ln9) sp. (Cw063)?

I picked these two out of a tank of C. similis, they appear to be Cw063, do others concur?

Re: New Cory at my LFS - not blochi?

These are lovely fish, I've always liked the cryptic squiggles of trilineatus and these have a similarly pleasing pattern but with a different form. The larger size, longer snout and white fringing around the dorsal spot really set them apart. I got three of them about a month ago from a good shop, ...

Re: Dianema urostriatum showing signs of spawning

Several years later, another tank and a new group of Diamena. The tank (garden tank 2 in my profile) has been set up for barely two weeks and the fish in it for just on one week, a group of 5 flagtails in with a bunch of corys. Temp 21 deg C, soft water with 30% water changes every other day; a dail...

Re: A couple more IDs - C. leopardus & C. bilineatus

Thank you Karsten that is interesting, I did not realise C. bilineatus was not readily available in the trade. I will get some better shots of my fish when they have properly settled into the tank.

Re: A couple more IDs - C. leopardus & C. bilineatus

I'm happy to go with C. bilineatus for the ln5 fish and the lfs has confirmed the others were supplied as C102 - I really like them and purchased an additional two today.

Re: Corydoras ln8sc4 identification

Thank you Jools and Eric, I look forward to watching these fish develop in the future, in the meantime I will try to get a better photograph of the first fish which has the black extending further up the dorsal fin.

Re: Corydoras ln8sc4 identification

Thank you Jools, much appreciated. If you would like higher resolution images of any of these to use in the catelog do not hesitate to ask.

Out of curiosity, what do you consider to be the differentiating characteristic(s) between C. ambiacus and C. agassizii?

Corydoras ln8sc4 identification

I would like help in identifying these five Corydoras, I believe there are at least two if not more species from ln8sc4, most likely candidates being C. agassizii and C. ambiacus. They were purchased from an online retailer who had them listed as C. punctatus with a stock photo of such, which they a...

Re: Identification - C. agassizii & C. leucomelas

Cheers, I also wondered if one of the former might be delphax, I will try to get a photo of that one.

The possible leucomelas had me stumped due to the amount of black in the dorsal fins.

A couple more IDs - C. leopardus & C. bilineatus

I picked these up from a proper shop the other day, marked C. blochi and C. napoensis but I beg to differ.

These I wonder if they might be C. leopardus or possibly a C number?

and these more likely C bilineatus?

Identification - C. agassizii & C. leucomelas

I recently got a group of corys from an online fish shop, they were listed and as C. punctatus but clearly are not. Upon raising this with the seller they conceded they were not the right ones and sent me another four which included one more of the same (C. agassizii?) plus three different (C. leuco...
