Understandable. I have five right now and am waiting on four more females to show up tomorrow. These five have previously lived with Danios, Bloodfin Tetras, Guppies, Cories, Rams and a SAE. They currently live with Danios, an Angel, a Gourami, a RTBS, a BGK and a BNP. They will not be aggressive toward smaller fish at all. They do look like they have large mouths but their throats are very narrow so they don't like big food. Again, they are very peaceful and not very rowdy at all. They are mid to top level dwellers and school nicely when kept in groups of five or more, though they will wander off on their own at times.
