re: Simon Forkel article in Amazonas no 42

I ordered an original German copy of this issue of Amazonas. They sure make better aquatic magazines in Germany and the Uk than in Holland :roll:

I have yet to read Simon's article. I just finished reading Heiko Bleher article that is also in this issue though.

In general I think his article is a great piece of information but there is one paragraph that I cannot agree with:
Heiko says that pt cf eimekei is a small pterophyllum species. Ok, can be, but: then he says that the red back manacapuru and Santa Isabel red back fish are all synonyms for eimekei. I can't agree with that. First of all there are significant and large differences between manacapuru and Santa Isabel. And certainly the santa Isabel angels are very big fish when fully grown.
I really wonder how Heiko came to these conclusions.
Video's of my Pt. Altum, Pt. sp. Santa Isabel and Pt. Sp. Rio Nanay:

Hi Everyone,

Simon's article is excellent and as I can understand German perfectly, I can confirm this. I should actually translate it myself and charge Amazonas, USA.....

With regard to Heiko's article, I can only say that I am disappointed. I agree fully with Joost with regard to the differences between P spec Manacapuru and P spec Santa Isabelle, I cannot see the connection. As far as I know there are also no P leopoldii in the Rio Negro as claimed by Heiko, as I understand they only occur near Santarem and in the Rio Essequibo which drains to the north into the Carribean. Then I find it disappointing that there is this attack on the early altum breeders time and time again. Just right now we have a thread showing true altum from the Rio Negro, but Bleher states that these are not true altum. What must we believe? Unless we have another source of information in the form of DNA data this will remain a discussion and something in which people will have an opinion which cannot be verified, but this sort of approach where "I definitely know" does not help us move forward. It would be good if someone could supply accurate and genuine material of the other "species" that Heiko mentions so that accurate comparisons can be made. For me this article does not tell me that there is any more evidence than three species of Pterophyllum, i.e. P altum, P scalare and P leopoldii.
