Mandarin Goby

[ReefJunkie01]

Had the mandarin about a month now....the six line wrasse was a jerk for the first day but the Goby was like "Ain't nobody got time for that". He was the bravest little fish I have seen. Very your and not afraid of many things he never saw before. Brittle star touching him, tiger tail crawling over him as he slept at night. No one bothers him anymore except the cleaner shrimp wanting to touch him.

Hopefully it's just the normal establishing of who's dominant. If the six line isn't harassing it anymore, hopefully will be ok now. The tiger tail may just also be establishing dominance for the ground coverage though. As long as no one's nipping at each other you should be ok. Just keep watching them and keep an eye on the mandarin to make sure he has no scratches or nip marks. The mandarin can do some damage when fighting back though, they have a lot more energy than they show normally.

Oh I can definitely attest to that, my female Mandarin in particular makes A LOT of noise when feeding on rocks. https://www.youtube.com/watch?v=YCIePo0xW-Q
Sometimes I can even hear the sound outside of the tank, and even mistake it for my pistol shrimp, really freaky.

They can also be particularly vicious if in a foul mood as well. When I bought my male I saw a small one at the LFS being bullied by the larger females, and one of those ladies grabbed him by one of his pectoral fins and literally trashed him around like a ragdoll! It was brutal.
