I did a freshwater dip on my female clown cause she was actin real strange, not eating for 2 days just hanging out basically laying on the bottom. I figured maybe it would help get rid of any parasites or bacterial stuff she had and I put her in the 1 gallon pitcher with the water and wondered why she was acting so strange and I forgot that I didn't add prime so basically she was in chlorine for 4 minutes...I'm a horrible person :-(
