Re: Cenote Cristalino, Yucatan Penisula, Mexico.

Wonderful videos indeed, thanks for posting.

However the sailfin molly is Poecilia velifera in my view.

Re: Tomocichla asfraci question

Thanks Michi! Allgayer (2002) states that Sung (1996) has found the species there, but unfortunately such a reference is not included in the bibliography. In a recent list of Costa Rican fishes ( http://www.checklist.org.br/getpdf?SL061-13 ), the species is not included. However, they list T. tuba f...

Tomocichla asfraci question

Dear all, I have a question concerning the distribution of Tomocichla asfraci : I have read somewhere that it should live, besides the known Panamanian localities, in the Rio Sixaola drainage in Costa Rica. While this would not be unexpected judging from the distribution of other fishes in the regio...

Re: Genus and species naming.

Sorry for digging out this thread again: Anyway what is the problem ? Naming from colors isn't worse than "Maylandia hajomaylandi" !! :? :lol: I couldn't agree more Philippe. The same applies to names derived from geographic origin. Hoplias malabaricus (Bloch, 1794) is named for Malabar (a region of...

Re: About Pelvicachromis taeniatus

In the original description of Pelvicachromis silviae , Lamboj (2013) uses the name P. taeniatus only for Nigerian and Beninese forms and treats P. kribensis as valid for Cameroonian populations (except the Wouri form, which is regarded as an undescribed species) without giving explicit reasons for ...

Re: Rio Tempisque

Thanks for the link, Lee. This area has been formerly included in a "Chiapas Nicaragua Region" but the fauna is quite different from the northern part (= Chiapas-Fonseca). Unfortunately, no full list of species is provided; and it should be noted that those mentioned do not occur in all rivers of th...

Apart from A. siquia, the following other cichlids are reliably recorded from that drainage: Astatheros alfari, A. longimanus, Herotilapia multispinosa and Parachromis dovii.

Re: A little help with an ID

This is Oreochromis aureus, a non-native species naturally occurring in West Africa, the lower Nile and the Jordan basin. It has been widely introduced to Central America and elsewhere, often with negative impact on the native fish fauna.

Re: Heros severus -The Mouthbrooding Severum With New Spawn

Darrell, I don't know what map you have, but if it places Rio Uaupes in Peru you should better bin it. In fact, it is a tributary to the upper Rio Negro in Brazil and Colombia (where it is spelled Vaupes). And the type locality of H. severus is in the upper Rio Negro drainage in Brazil, not in the O...

Re: Andinoacara - Green Terror - Here we go again!

I agree, both are A. rivulatus . This species is - at least in some populations - polymorphic with regard to the color of the fin margins, i.e. white- and orange-margined fish have been observed in the same habitat. Males of this species have the colored caudal fin margin typically broad and somewha...

Re: Congo Cichlid ID Help

I agree, this is definitely not P. congicus. They look like young Oreochromis niloticus, a species not native to the Congo basin (except Lake Kivu and Tanganyika) but introduced to localities in the lower Congo drainage.

Re: Ctenochromis polli and C. luluae

I have kept this species several years ago (unfortunately only for a short period). It is certainly aggressive towards conspecifics but not more than Pseudocrenilabrus or most other riverine Haplochromines I had so far. I have made the experience (also in Pseudocrenilabrus and other haplochromines),...

Re: Ctenochromis polli and C. luluae

I concur with Mark, the fishes shown on the photos are clearly C. polli . They agree in every respect with the fishes known for many years in the hobby (in Europe, they are known even longer and appeared first in the 1960s) under that name. Likewise, they agree perfectly with the original descriptio...

Re: Geophagus parnaiba and G. 'Pindare'

That's indeed a good question, Ingo. There seem to be only minor, but apparently consistent, differences in color, mostly the presence of iridescent markings on the cheek and the more regular fin striping in G.parnaibae and the more intense reddish longitudinal stripes on the body in G. sp.
