Bałagan wynika z kilku czynników. Jak na razie brak jest miarodajego ostatecznego opracowania rodzaju Pterophyllum z podaniem gatunków, form i ich występowania.
Systematycznie mamy:
P. scalare has 23-29 dorsal rays 24-28 anal rays and 30-40 lateral scales
P. altum " 28-29 " " 28-32 " " " 46-48 " "
P. leopoldi " 29-32 " " 19-22 " " " 26-30 " "

Przeglądając fora i linki na temat altumów znalazłam coś takiego:
http://forum.practicalfishkeeping.co.uk/...hp?t=77066. Na końcu wątku jest opis.
For a summary we have: Altum will frequent three different biotypes, that is:
1.The Alto Orinoco or Rio Ventuari type, characterizee by clear water with a significant water movement and hence oxygen turnround, as well as medium temperatures near the High 70's and mid 80's.
2.The Blackwater Creek or Rio Negro type, where water current maybe somewhat slower, but also plentiful in dissolved oxygen and where water temperature is similar to the Ventuari Biotype.
3.And to the North, towards the Llanos, Altum will frequent slower moving clear blackwaters in the Caño Llanero biotype. These waters have relatively high temperatures, up into the 90's on a hot sunny day and in the dry season, may have a lower O2 count.
