Thanks!

Back in Europe and just wanted to say a big thank you to Don, Lew, Marc and all other from OCA I had the pleasure to meet.

I really envoyed my stay and was very impressed by the size and the organization of the Extravaganza, and not least the very friendly atmosphere. Thanks for inviting me!

Re: Herichthys pame, H. molango & H. pratinus

Juan Miguel, As I understand samples were collected at Guayalejo ('red spotted labridens'), and these are still regarded as riverine H. pantostictus? What about the 'blue labridens' from Coy, Pujal etc - were these included in the analysis? What's your opinion on that some of the populations of rive...

Re: Photos of X. sp. red princess in its natural habitat

Adrian, have you read Büscher's article on N. wauthioni? A most interesting read, apparently N. wauthioni and N. ventralis are very closely related:

Büscher, H.H. (2007) Neolamprologus wauthioni – ein verschollener Buntbarsch aus dem Tanganjikasee. DATZ, 60: 58–61.

Re: Two lake Victoria cichlids described

The name "argens" was previously used as a temporary trade name, and was never seen as a formal scientific name, until the formal paper coming out the other day,much like the situation with Neolamprologus sp . "walteri" becoming Neolamprologus walteri once formally described. Mark, it is not the sa...

Re: Two lake Victoria cichlids described

The description list at least seven previous publications where the name Haplochromis argens has been used without a proper description, which would make the name a nomen nudum aka not available. Can a later author correct this, use the same name in a publication that meets the formal requirements, ...

Apparently the name Haplochromis argens is not available, as it has been used in a previous publication without a proper description - anyone that can shed some light on this? The CRC catalogue states this in the profile of Y. sp. argens: In the caption of figure 7, the fish appears as H. argens but...

Enrico, Reganochromis? Hmmmm,don't think so, not with a such a pattern in the dorsal fin and the spots along the longitudinal line - but admittedly, the mouth region has some similarities

Re: Enantiopus?

Sorry Bruno and Lisa, I offered to do a translation, but has been busy for a few days - my bad :oops:

To me the photo show a young Enantiopus melanogenys male - the depth of 50 meters is not that common for Enantiopus, it has been recorded several times out of the breeding season.

Hello Bruno, and welcome to the forum. I found the photo and have attached it here: 286658_375068425916619_910920459_o.jpg To me it looks like an Enantiopus, but I agree 50-55 meter is rather deep for the species.

Re: New Andinoacara

Semantically therefore, something cannot be "more correct" or "less incorrect". Sure it can, Willem. In German, Danish, Swedish and probably several other languages. I'm surprised you can not write that in Dutch, as they are all related? I certainly read 'richtiger' as 'more correct' or 'more accur...

Re: Greenwoodochromis bellcrossi in natural habitat

Thanks for posting the pics Adrian, and to Angel for sharing them!

I'm glad my speculations turned out to be correct :)

My specimens came from the Brichards in Burundi, but they have been collected at Chituta Bay a few times as well.
