Recently got this mandarin and noticed after about a week in my display tank that his tail has begun to get eaten away by something. I have sense moved him to my quarantine tank. Given him a freshwater dip, the quarantine tank gets daily water changes, and he is eating the copepods I have added to the tank. He has been in quarantine by himself for 3 days now and it appears as if it's slowly getting worse. Does anyone know what could cause this? Is there a more effective way of treating what is happening to him?
Any help is appreciated!
