One of the nicest types from Phillip Voisin & Co.'s trips to Venezuela is this; Yellow Top Snake Chest from Cumana Center City 2013. It has been linebred and spread in the hobby from some talented guys in Italy.
I got them last year and it is stunning to see them in the tank as a big group.
A bit of variation is found too:
...a bit of flame tail.
...and some without.
