[zeigetsu]

I've bought a new fish for my tank it size is around 12-14cm,the seller told me it's an acestrorhynchus falcatus , but it doesn't look same at all ,at first i thought it was a acestrorhynchus falcirostris but when i look a bit closer it has a metallic green line along its body and very small dot behind the gill ,and also the fin's doesn't has a red or yellow color, shape of the snout is similar to the Goliath tiger fish and the shape of the body is a bit bulky I can't determine what kind of acestrorhynchus is this,anyone can id this fish??


Here's some pict of it



Sorry if my English isn't good enough

It might be stressed out. Let it settle and will color up usually. Then can tell for sure. I think it could be lacustris with a green shimmer but not sure as there aren't a lot of info and seen too many specimens.

Most of the time red tail cudas coming out of the lfs are falcatus. About 90%.
