Thank you Jools and Bas

Marcos

Of course Bas, what I meant to ask is if you can teach me what to pay attention to in order to tell a male from a female.

Marcos

Bas, how can you tell the female from the male when they're so young?

Viktor, to count the rays in the other fins I'll have to wait a bit, since -being only recently brought home- many of their fins are rather torn, but it takes a short while to recover. It's an interesting means of stating if they ...

And two more... thanks Viktor for persuading me to use the flash!

Well, I could get a pair of better pics. So my question is: can these two be the same species? Why such difference in colour -that has remained unchanged since I brought them home last Sunday, and under differente lightings?

Viktor, I'll try and take better pictures. Bas, have you got any pictures yourself?

Marcos

Thanks, Viktor. But it is the same species as yours, I'll show you another pic:

Here's another angle. I'm sorry the picture's not good, I didn't want to stress them much. Far back, under a rock, a young Heptapterus mustelinus.

And today, at the local fair, I came across these two little beauties in a group. To me, they're both Rhamdia, but why such difference in colour? They loooked like that in the tank, and they continue to look as different here at home. I can't post more than one pic at a time, so this one's from above:

Well I've had this Rhamdia quelen for over a year now, it's grown to 22 cm and it's doing quite well in the tank it miraculously shares with a Crenicichla lepidota. Bothe species are endemic to my country, they dwell with no problems even in low temperatures (even 10C!)

I know for sure it came from the province of Buenos Aires, but not much more than that, for sellers won't reveal their sources...

Hi all, here's my new Loricariichthys anus . I thought you might all like to see pics of this species that is not so common in the hobby. It's an adult I bought a couple of days ago, wild, here in Argentina (near La Plata). It's quite long, 250mm. It's very slowly getting used to his new aquarium ...

Oh my! 150 mile round trip to get them! It sure was worth it, since you've had so many offspring...
Vicky, thanks for all the information.
All of a sudden, my Lepthoplosternum have become extremely bold, eating tubifex form my hand on the second night of arrival. Couldn't quite believe it. They ...

Hi Vicky,

thank you so much for your help. The spotting pattern of your Lepthoplosternum is exactly like mine, as far as the fins are concerned; because in my case the base colour is a reddish chestnut, as I happen to see now in dayight, but we can point that as variability according to biotopes ...

Thanks, Silurus! That´s been most helpful...
As soon as I get a snapshot I'll post it here

Oh, yes, I can see them very clearly. Have you got any photograph to post?

Marcos

Hi all, I just bought two Callichthys callichtys and two others called " Hoplosternum littorale ". As soon as I spotted them in the LFS, I noticed the caudal fin was not v-shaped, but rounded like that of the Callichthys. But they were definitely not young callichthys, I could tell by the size and ...
