I wish they had an english generator on that site...only could read the scientific names, or whenever marcus or another english speakin person wrote. Very awesome photos, very very accurate ID's...awesome fish...
Those percana are indeed awesome, as well as your acutes marcus...always have loved them...
...that does seem a little odd. There are several species of cf. sp. 'belly crawler' though, so its very possible that it is another type of fish or the collection area is different.
