Experimental model and subject details Zebrafish husbandry Zebrafish were reared at 28.5 °C in 14–10-h light–dark cycles (conductivity of 1,000 μS, adjusted via Instant Ocean Sea Salt (approximately 30 g l−1), pH 7.0, adjusted using sodium bicarbonate)69. Zebrafish from 5 to 14 days post-fertilization were fed rotifers and used for experiments. All experiments complied with protocols approved by the
