Nannacara "Sou Mou Rou"?

[yorky]

Hi,
Recently one of my local fish shop brought in several male adult fishes labelled as Nannacara "Sou Mou Rou".
Unfortunately no females were available.
According to the shop owner, his supply came from a German breeder.

Its a very nice fish very much like the Nannacara Aureocephalus.
Anybody came across such a Nannacara species?

Searched the internet but to no avail.
Guess one way is for me to buy a male and takes photos to id..
but would prefer to buy fishes in a pair.. :lol:

This is Nannacara aureocephalus:

Are they Nannacara anomala?

yorky,

WELCOME TO THE FORUM

Well,
I certainly am not aware of any Nannacara species called "Sou Mou Rou". That doesn't suprise me though, as new fish are showing up all the time. It would be most helpful for us to have a pic to maybe give you an idea whether they are one of the existing species or a new one. Nannacara can be quite non-dimorphic, so it is possible that there might be a female in the tank. But supplying one one sex of a new fish would certainly not be unheard of for breeders. This insures that they "hold all the cards" for longer.

I just got a copy of Wolfgang Staeck's latest book (Thanks David, the check will be in the mail tomorrow) and it has this fish in it. He calls it N. sp. Sourourou. It is the same species discussed in Stawikowski & Werner's (1998) book as N. sp. Mana. To me, N. sp. Sourourou looks like a color morph of A. aureocephalus (both are found in Crique Sourourou in French Guiana. The difference is that N. sp. Sourourou has more dark mottling on the face where A. aureocephalus has a mostly gold face, and N. sp. Sourourou can show a series of reddish brown stripes accross the body similar to those seen on the flanks of A. sp. aff. agassizii Tefé. Whether this is sufficient enough to make N. sp. Sourourou a species separate from A. aureocephalus will depend on more detailed examination of it distribution in relation to A. aureocephalus and possibly cross breeding experients. For now I'd keep it as a separate 'form', related to N. aureocephalus.

Owen, Mike & Neil,
Many thanks to your information.

Mike,
The description you gave about the differences between this fish and the N. aureocephalus is exact.
By the way, what is the title of the latest book by Wolfgang Staeck?
I would definitely like to get one too!

Hi, living in French Guyana, I know this fish from "crique Soumourou" and "crique Malmanoury" near the city of Kourou (Here, we say "crique" for the little rivers). Some authers call it Nannacara aff taenia (because of the series of reddish brown stripes), Nannacara aff. aureocephalus or Nannacara aureocephalus.

In fact, in captivity (after 6 month), making the difference betwen this fish and the real N. aureocephalus from "crique Laussat" (Type locality) is really difficult. So, I'd call it Nannacara cf. aureocephalus considering it probably like a local form or an "écotype" (I don't now the English world).
