I just fed my Formosa commune of three. I threw in 6 undersized lateralis (I like watching them hunt so instead of feeding 3-4 properly sized feeders, I give more but smaller). Two of them literally jumped onto the lats. One of the two actually tackled 2 more and had 3 small lats in its jaws. The second Formosa was content with its single lat (the lat was one of the larger ones that were thrown in). The last Formosa, I just noticed, is in pre-molt and didn't show too much interest in the roaches.Terrestrials. Arboreals are annoying because they can't just be tossed in a critter keeper with some substrate and a water dish, you have to give them stuff to climb on and find some kind of container that's tall but still nice for viewing. I like the ease of terrestrials. Also arboreals are too fast and jumpy, and so many of them web/hide. And you never know when they will eat so it's harder to catch them in the act. Terrestials pounce once a bug walks up to them, which it will right away. Arboreals either have to wait until the bug decides to crawl wherever you are or they come down, usually once you are gone.
Plus so many terrestrials are docile. I think docile is a plus.
On the other hand, those pokies sure are lookers...
Feeding terrestrials is definitely easier - I love watching my L. Parahybana grab its food from my tongs and do a little dance - but there's nothing compared to my pokies jumping from one side of its enclosure from the top to the other side of the enclosure to the bottom. Simply astounding!!!
