What methods did they take to prevent predators from impacting the experiment?

• Performed 24/7 surveillence

• Surrounded the experimental anemones in cages

• Dascyllus trimaculatus has no known predators

How did they analyze the hiding behavior?

• Watched the fish in-person

• Used thermal imaging to detect fish

• Utilized sonar to detect fish movement

• Installed cameras to take videos

What is ventilation rate?

• Measure of opercular beat rate

• Measure of gill movement

• Measure of oxygen concentration over time

• Measure of snout movements
