Re: White worms in eye

Hi Javier Sounds like your fish has eye flukes, a very common infection of digenean trematodes. Eye flukes can impair the fish's vision, but the fish being an intermediate host, these infections do not typically have severe health consequences, especially in captivity where there are no predators. A...

You say that. And I am not sure what side you are referring to.... I guess that's what we call job security?

Re: Impressions from recent trips

Thanks, Rico! I didn't know that. We caught several females with spots, hence, my suspicion that it was A. rhytisma.

Re: Impressions from recent trips

Hi everbody Thanks for all the feedback and questions. Rico, are you sure about that Astatheros female? I find it a very odd fish. The lack of black spotting really doesn't with with A. bussingi. Note that this was the only unspotted individual that we caught at this site, and A. rhytisma has been r...

Impressions from recent trips

Hi all I used to share pictures from recent collection trips here on a regular basis. For some reason, that stopped once I got a real job (I wonder why). In any case, we had some fun trips to Mexico and Costa Rica this year, and I thought some of you may be interested in some of our catches. There a...

Re: Taxonomic Status of Amatitlania coatepeque

I have a PDF. If you send me a message with your email, I can send it along. I would not be holding my breath for A. kanna and A. siquia. I think those are pretty solid.

Re: New genus 'Nosferatu'.

Back to more serious stuff. Some remarks about the (as yet unpublished) paper. Many memebers of this forum would probably agree that the (former) labridens group can be easily distinguished form the other Herichthys species. The molecular results of the study at hand confirm this. What I do not qui...

Re: Rio Danli

The problem with stream names in Central America is that they're often not formally named and people refer to them by the name of proximate towns. I.e., the same stream might have different names as you travel along it. That's why it is important to georeference collection localities.

Re: New genus 'Nosferatu'.

The feeding behaviour can't be a reason to separate genus. To be fair, aspects of trophic morphology (not behavior) may have influenced the etymology, but the call to split Herichthys is also supported by other (long-established) evidence (phylogeny). Notwithstanding, it is kind of a cheap shot to ...

Re: sexing CA dither fish

Hi Andrew, as already mentioned, Brachyrhaphis are easy to sex visually; the males will have a gonopodium and the females a regular anal fin. I disagree though that Astyanax can be sexed by body shape (got some data on that somewhere...). But there is an easy trick: males have microscopic hooks on t...

Re: Rio Monga, siquia or nigrofasciatus?

Our analyses have shown that - at least morphologically - the Rio Monga fish and similarly colored populations (e.g., from the Danli area) closely resemble A. siquia from Costa Rica and not A. nigrofasciata from geographically closer Honduran drainages (see figure). How all of these populations are ...
