That's a good sign. It means they are now outgrowing your tank in the sense that they are defining territory and the large one has marked the whole tank as its territory. Actually, I'm only surprised they didn't start fighting sooner. The fishes must have gained quite a lot of mass since you first bought them. No surprise to me.

Agreed, I thought this would happen sooner. I guess it went long enough I thought it might last, but that's being naive, I suppose.
They have gotten a lot bigger, the big one being too large for my tank really. He's gone to a 6' tank now, so hopefully he continues to do well.

After a long and joyful(?) experience with these guys, my frustration level at the SPS nipping is reaching critical levels. Really close to re-homing this guy, assuming I can find a good home. Stoopid fish :(

Aw. Thats to bad Brad. Guess one has to make the choice eventually.

What about getting rid of just one and see? My nips at Sps when it gets hungry. Little nuggets got me trained to feed him.

He's already down to just one and is still frustrated

Missed a couple of pages lol whoops

Don't mind him... He works two jobs and is probably still pickled from Tuesday night. I know he has a beautiful MI in his tank and its predominantly an SPS tank so it can be done.

Oh, for sure. Tons of people in the MI thread on RC have done it. But both of mine are non stop eaters. I hoped once I got rid of the big one the little guy would stop, but nope :) And if I feed him, he eats the whole sheet of nori in 20 minutes and goes right back to eating coral.
I have a home lined up, hopefully it works out ok for the fish.

Now I need to figure out what to replace it with.
