I had a pink gonio in my 125 that was doing ridiculously well. Seriously, when extended, it was big around as a bowling ball and looked like a woman's flowing hair in the water. It was huge and healthy until the maroon clown decided he was going to take it as a host.
I moved it in the tank several times but the clown would still bother and pick at it every day. Despite this and the Powder Blue Tang taking bites of it occasionally and being moved 20 times - it still did well.
Finally yesterday, I had to dispose of it when brown jelly formed around it's base.
