There is no way that is an S.
ocellifer. Unless the image is really messed up, that fish is definitely the
decorus. The tail markings, hump on the back, and the spots themselves look nothing like the
ocellifer's.
Decorus have flaged tails, like the one in the picture,
ocellifer do not.
Decorus also have elongated mouths (circled in the picture) with white whiskers and
ocellifer do not.
I seriously think you should compare these two species again. Another obvious difference is that
ocellifer only gets 7"... clearly smaller than your fish.
I may sound a bit obsessive, since most synos are basically the same, but having kept a
decorus for years, I know what they look like and that definitely is one.
