Nice to see you too!
I call this tank the "drama box", as there is always something going on that makes my heart skip a beat. The crabs will try to eat everyone, but luckily they are slow and clumsy vegetarians, so as long as there are lots of algae for them, they just threaten and grin. For the most part, everyone seems to be able to stay well and safe.
Ursula Flerkin, the anemone, is the biggest threat. She has already eaten a hermit crab and tried to eat the crab molt, only to later realize it was empty!
This is a fast video of the spit back moment:
There are around 20 tidepool sculpins. They started at around 10mm in size and some are now about 25mm, not quite coloring yet except for this one being the oldest and around 30mm:
