Effects of elevated CO₂ on predator avoidance behaviour by reef fishes is not altered by experimental test water.

ABSTRACT: Pioneering studies into the effects of elevated CO₂ on the behaviour of reef fishes often tested high-CO₂ reared fish using control water in the test arena. While subsequent studies using rearing treatment water (control or high CO₂) in the test arena have confirmed the effects of high CO₂ on a range of reef fish behaviours, a further investigation into the use of different test water in the experimental arena is warranted. Here, we used a fully factorial design to test the effect of rearing treatment water (control or high CO₂) and experimental test water (control or high CO₂) on antipredator responses of larval reef fishes. We tested antipredator behaviour in larval clownfish Amphiprion percula and ambon damselfish
