Fisrt off, let me say that I love this thread and have followed along since Lemon's first post. I appreciate all the time and effort put into providing information and updates.
Lemon - based on your last post, I think you are back home now and spending time with your beautiful pair of paucifasciatus. How is it going? New pics to share?
Gasman - how are your mertensii doing? I can't remember if you mentioned the corals you are keeping in the system with them. Any significant munching on their part? I have been considering trying one of these along with a CBB and a YLN, but would like to know what corals may be in danger if I go with it.
Finally, can any of you speak to experience with either a falcula or a semilarvatus butterfly with corals? I have seen both of these categorized as "reef safe with caution", but understand that it varies from fish to fish as well as it depends on the corals/inverts in the system as well.
Beyond the CBB and YLN, the mertensii, falcula and semilarvatus are the three that intrigue me the most because of their beauty, availability and price (the semi is a stretch, at that). If I could get my hands on a marginalis, I would probably jump on that, but they seem very scarce in the trade in the US.
