Interesting thing I saw last night, my chromis seems to nibble on my Fox face, not actually biting it or hurting the foxylady, but it seems they are cleaning the foxface like a cleaner wrasse , has any one seen something similar ? i dont think its territorial issue as the Foxface just stays in one place so they can do the nibble dance or what ever they do. and then it swims on...... no visible damage to the fins and the foxface is healthy and happy. just very weird ???
