I missed those exhibits for various reasons that I'd rather not share, but I feel that I had a decent trip there.
I don't think it's the pond exhibit.
A sign for the anemones said "First Time On Exhibit! The Zoo pioneered a technique for growing Tealia anemones. Born the size of pinheads in 2010, these young are now big enough to join the adults in this tank."
I do not know about the exhibit change in the tarantula terrarium, I just saw a sign.
Thylo and mxttfan- The Sand Cat exhibit is in the Small Mammal House, right before the first Meerkat exhibit. I didn't see the cats myself.
It's ok about the bear cubs. I really had hopes to see the Andean cubs though.
Were the anemones on these small shelf-like structures? Interesting about the Sand Cat.
