As are false SAE's, which are very similar to SAE's as well. Their fins tend to have a yellowish tint to them and they have 2 sets of barbs instead of one. I have the false ones and they have to be kept separate or they spend all their time attacking each other. Of course mine lives with my cories and hangs out with them a lot, even when they were all in the 10 gallon tank. An odd fish but funny. They tend to swim quite jerky and generally like to hang out on the bottom or the sides of the tank nibbling away.
