Aggressive yellow clown goby

[Jason K]

I have a yellow clown goby and pink streaked wrasse in quarantine (7 gal tank) for approx. a month now. The clown goby is very nippy towards the wrasse.that is twice his size, especially around feeding time. The wrasse seems fairly unphased by it all and shows no physical damage, but any cause for concern?

They are going to go into a 14 gal reef where they will be the only fish. Would you not put the goby in the tank? Or maybe introduce the wrasse first?

Yeah they can be little meanies. Introduce the wrasse first.
It's a small tank so you'll be able to easily remove either fish if needed.

The clown goby’s aggression has gotten so much worse and he’s gotten a lot bigger as well. It really seems he wants to kill the wrasse.

I had to install a tank divider to get the wrasse some peace. I tried removing the divider after two week, but the same level if not more aggression.

It’s almost time to introduce the fish into the main tank (running fallow for ich), any chance the behavior changes? I’m leaning strongly to not even introducing the goby to the display.

So wrasse went in first, goby followed a week later, and the behavior is night and day in the display vs qt. Almost zero aggression and they been in together for three weeks now.

Mine is a fourth the size of the wrasse. Yellow coris runs away but hardly seems to care much.
