New clownfish

[Brooks Allman]

my black ice clownfish got into my DT two days ago. It has developed a small white mark under its bottom lip. I think it’s from rubbing on the glass and being in a new environment. Any experience with this? Healthy and eating just has the ‘rub’ mark under his chin.

Also he is ‘yawning’ every once in a while.

Pictures please, it’ll help in identifying it

From my experience I've seen those marks do to their behaviour, most often it is because of rubbing against a hard surface, just keep a close eye on it and make sure nothing appears around its fins or eyes. That's where you will find the first sign of a decease like brook or ich.
