I purchased a tank from someone selling it locally. It was a 20 gallon fully stocked tank for $160, so needless to say it was a steal. However, now that I’m home with the livestock I’m realizing that the small mocha clownfish of a pair is missing an eye. It seems to be healthy outside of the fact. At first this scared me, but now it’s kind of endearing. I just hope it’s not sick or in pain at all. The pair came with a wrasse that seems to be pretty territorial. I’m hoping it’s not the wrasse that did it. I may try to trade it in if it becomes an issue. Besides that, any thoughts on what this could be? Will the clown be okay? Link below is a photo
