Duck tip: They should have a water bottle instead of a dish. Their down is like a sponge, and even if it's shallow they don't always have the sense to get out, which can result in hypothermia. Plus, there's nothing cuter than part-way filling a bathtub so the ducklings can touch on the shallow end and swim on the deep end, then dropping in a dozen guppies and watching them dive for them.
Nice new additions, that's a really nice looking bumblebee.
