Well I think this thread has almost nothing to do with my original post anyway :wink:

They seem to get along fine, although I rarely see my lawnmower. The bicolor has been with me since the beginning, so I can imagine it getting territorial if it could, but the lawnmower is twice its size :)

Yep it is a gold rim tang A.nigricans.
How long have you had it?
Your picture shows lots of coral in your tank.
It may need more room to swim and that is the reason it is circling

naesco, I've had this fish about 4 months now. Previous to that it was in the LFS for about 2.5 months. They had a really high price on it, so it didn't get sold. I watched it get fatter as time went on and thought it was a good choice. Since it was different than the last one I had, I thought this was the species that did well. The LFS confirmed this (doh!).
So now I have a tang swimming in circles. It eats like a pig, shows growth and does still graze around the tank, but the last 2 weeks has been mostly circles.
I've ordered a Tunze stream and hope that increases the current and O2 in the tank. There is still a fair amount of swimming room. The fish have full access behind the rocks. I had a trigger that did the loops for a while, and then stopped. I'm hoping this guy does the same.
Since I have the largest tank amongst the people I know in Victoria, finding a bigger home isn't an option.
I'll have to make a decision after the Tunze pump...hopefully it helps.

Um You have not had it that long. I think over and above what you are doing I would try to feed it a variety of foods including live and the sponge type foods. Good luck

I agree. I feed probably 5 different types of food regularly. Formula 1 & 2 frozen, mysis, spirulina, pellets, seaweed selects. Once in a while I put some banana in there. Mostly the chromis like that. This fish does gainweight/size and overall seems in good physical shape. If I see it declining in health, I will pursue a bigger home for it.

How do you go about feeding banana Brad? :?

Deb,

Get to bed, you have an early flight......

It was a serious question....and btw...I can't sleep.... :shock:

hehe, just cut a slice and hold it in the water. The fish pick at it and break off little chunks.
