As lovely as that tank is, I agree with others that even for a large terrestrial such as an LP, the style (I. E tall rather than flat) is really better suited to a large arboreal. P. Regalis can grow big and the singapore blue tree spider is also a large species up to 8 or 9 inches DLS so will be an impressive sight. I am never convinced with the colony concept but I know some have been successful. If decorated with many plants and branches, hides etc, you will have a really good looking display tank regardless of whatever is in it. Down side being for a terrestrial, if you have stuff to climb up, they probably will and therefore you increase the risk of a fall as they are not as adept climbers as the arboreal species that have evolved that skill. I hope this is useful. Keep us updated with how things progress ☺
