At what size does the Vieja Synspilum color up and start to get the red around the head region? I have an opportunity to get one for $20 and its about 4.5" to 5". Its in a lfs tank with some rose queens and other assorted cichlids that were donated and has a hint or red around the head and red through the rear of the dorsal fin, anal fin, and tail fin. It looks like either a Synspilum or a hybrid, not sure. Because it looks a little stressed in there, not sure if the true colors are showing.
