Hi Kaj! Your friend probably got hold of Ap. sp. "Tucurui". I've been looking for that species since I first saw it in Linke & Staeck's book. It has quite a unique look. There's also pictures of it in the Aqualog, South American Cichlids II. Linke & Staeck state that it is fairly easy to keep and breed. It seems to be appearing quite frequently in the US but very rare here in Sweden. Let's hope your friend is successful and manages to spread them around... Regards, Fredrik
