Re: New species: Vieja coatlicue :-)

Actually the name is not valid right now. The current publication doesn’t fullfill the regulations of the code.
Nevertheless, I think it is the ‘species’ which is known as “sp. ‘Coatzacoalcos‘ “.
I would like to read opinions by experts of these fishes.

Very interesting paper. I just wonder if it is ‘Laetacara dorsigera’ or (more likely) ‘L. dorsiger’.

Re: Crenicichla vaillanti and other French Guyana saxatiloide pikes

@Rico: Thanks, it makes sense.
Anyway, I think C. saxatilis and C. vaillanti could be synonyms.

Thank you.
Yes, it is very possible that these specimens are hybrids. The 'rheophilic morph' looks very similar to the hybrids between grammodes and hartwegi pictured by Buchhauser (DCG-Informationen, 1999).
