Thank you for the help and advice Jake.

I'll take all of the above in consideration and will do my best to convince her that it's not a bad idea to get some more T's.

Just an update:

List of T's on my wishlist for the expo and perhaps before then:

P. Regalis (After my first P. Regalis passed away, this one made it into the list)
P. Ornata
P. Cambridgei
L. Klugi/Paryhabana (still deciding on these)
A. Geniculata
A. Versicolor

Ps. I've convinced my girlfriend to get more T's. In my own words "They don't take up too much space when they're small so why can't I get a few more?" Hahaha. Didn't even mention when they're all grown up, but that's a discussion for another time.
