Thanks everyone. Here is some more info. I got the two cinnamon and the PBT at about the same time. One cinnamon has grown from about 2 inches to a really fat and wide 4 inches. The other cinam,on has grown from about 2 inches very very little. The PBT is about the same size as the cinammon having grown at the same rate. They have been together for ten years and within the last week the cinammon said this is my tank and I am after you PBT. This is 180 gallon with just those three fish and inverts. Important point, I started with one bubble tip 10 years ago and they have spread thru the whole tank maybe 20. I think this has triggered the cinammon to think with all these bubble tips it's now all my 180 gal. The clowns spawn frequently , and the little clown hangs with the eggs but nothing ever happens. I am sad I think I will lose the PBT. The clown has become deranged. I have been feeding them the same for 10 years, only change is the anemones have really spread.
