Re: Cory ID

Hi,

difficult one, could be C. agassizii, but usually it's not so pale.
Is this the normal colour of the cory or is it stressed ?!
Perhaps also C. crimmeni (this species is quite variable in colouration):

Hi Tommi,

unfortunately there are no information about sexing Hopliancistrus species.

Re: A list of pl*cos that i would like to know about

Hi, L 14, L 168, L 200 HiFin and LoFin has already been bred; L 236 and L 250 are very rare species, most of the fish sold with this label are in fact different species. L 600 is not a valid L number, P. leopardus and L 114 has also been bred. As already proposed, I would also suggest to start with ...

Re: Leporacanthicus sp.

Hi Tommi, It would be nice to have that Wels Atlas 2 translated to english already. What exactly do you want to know, I could translate a bit... L 263 is closest, even though the color is usually a bit more brownish and in the dorsal and caudal fin it's lacking the typical clear/dark markings. Here ...

Re: Laser green cory (male or female)

Hi,

I don't think that the small L66 would stop them to breed unless you adapt the temperature according to the needs of Hyancistrus species.
These two species don't fit, green stripes seem to need cold water to breed (below 25°C) and L66 need warm water (above 25°C).

Regards,
Karsten

Re: C 41

Hi, I was not aware of the fact? that this term is not used in a biological sense in English (in German it is, although dimorphism is more commonly used), dichromatism would be more precise (at least I just wanted to refer to the colouration and not the shape in the first place). However, is it poss...

Hi, yes, I mean sexual dichromatism/dimorphism. I've not yet seen this button, very useful. However the only new information that I found (I love Corydoras): "Notes:This species has been bred under aquarium conditions." So it has been bred. Yes, if no one answeres here I eventually mail th...

C 41

Hi, is there currently anyone keeping C 41? I'm quite sure that I have two of them with a length of ~2,5cm. Here's a picture of mine: http://www.l-welse.com/reviewpost/showproduct.php/product/958/cat/6/limit/recent/date/1214594295 Can you confirm the C-number? They were in the same tank with C. meli...

Re: A spawning from C. Schulzei

Hi, i find it hard to believe any corydoras species would breed in a condition where there's nitrite in the water. well that's not quite correct, sometimes it's exactly the condition that you can find at the end of the dry season. Low water level, bad water quality because of lots of fish starving.....

Re: Panda and Sterbai cories hybridising?

Hi, I have already seen pictures of Panda x Sterbai hybrids (they look somewhat like Sterbais with the black precaudal blotch). So I think one-in-a-million is a bit exaggerated. Especially Panda males are quite obtrusive. With other combinations (without Pandas) I would estimate the risk to get unwa...

Hi, I was following a thread on another forum (I'll see if I can find it when I get back home) that described albino-ism as a 2 gene combination - one for color or not and one for albino or color. The thread pointed to some published literature. that's interesting. Could you give some more informati...

Hi,

as mentioned before you should try with warm water and minimal hardness (I always breed them with 27°-28°C, KH 1-2).
They sometimes also breed in my other tank with 25°C and KH 6 but then I have large losses.
They need caves (clay, wood, schist) but are not very choosy in this aspect.

Hi, I disagree, my experience is that they grow faster than regular bristlenoses. This might be due to the higher temperature (27-28°C in my tank compared to usually ~25°C for regular BN) at which I keep them. At least I never had a regular BN with 10cm after just one year. But they are larger when ...

Hi Vriesea,

I've had 5 L333 in a 100l tank without any problems. They are not very agressive, as long as you have enough caverns (mainly occupied by the males, more than fish) and some additional hiding places for the females.

I wouldn't expect any problems.
