Leigh Clayton takes care of the health of 1,500 animals in Baltimore's National Aquarium. She explains how you can tell when a fish is sick, and everything that goes into keeping them healthy. She also tells us about how the National Aquarium connects to and educates about local species, and shares some tips for home aquarium care.

In a Slate Plus Extra, she talks about caring for Jacob Brogan's favorite animals: octopuses. If you’re a member, enjoy bonus segments and interview transcripts from Working, plus other great podcast exclusives. Start your two-week free trial at slate.com/workingplus.
