A LTA will host but it's not an Occy symbiant and I don't see one in your pics, rather 2 Condies and a BTA.
Crispas and Malus are "easier" than Mags imo, but I wouldn't consider them beginner nems. I'd get the nem before the clowns so it has time to acclimate to the tank before being pestered by clowns.
