I'd say false SAE, actually. I'm not aware of a false CAE, only the actual CAE itself (which this isn't). Fairly similar to flying fox in most aspects, but all three siamese algae eaters have different taste in algae (false SAE, true SAE, and flying foxes get mixed up constantly at the LFS, makes a nightmare for somebody like me trying to track down a specific species), not as large or aggressive as a CAE.
