ill quote from the page "Also known as the Domino Synodontis or the One-spot Squeaker, several regional variants of Synodontis notata are known, some of which have 3, 6 or 12 spots and others none at all. Some of these are seen for sale under the invalid name S. ocellata. It is also often imported with similar species such as S. nummifer or S.congica. These are usually then all sold as notata.
Synodontis notata is more active during the day than many Syno species and therefore makes a good addition to aquariums with more boisterous inhabitants."
