				Procedure: 1. Select embryos that are at the dome/30% epiboly stage stage (Figure 1). 2. Prepare three separate petri dishes that contain normal zebrafish embryo medium, a 2.5% ethanol zebrafish embryo medium solution, and a 1% ethanol embryo solution. 3. Place at least 10 of the selected embryos into each of the petri dishes and let them sit for 3 hours. 4. After 3 hours has passed, place all 3 sets of embryos into petri dishes with normal zebrafish embryo solution. 5. 24 hours later observe embryos for abnormalities and photograph them.
