I have had a Red Sea Max 130D for around 4 years and my first two fish were a pair of Perc Clowns. They have always been really friendly apart from a 4 month period a couple of years ago when one kept chasing the other until it would jump into the skimmer cup.
Anyway, the last few weeks one of my clowns has started attacking me when I put my hands in the tank and today it actually nipped me and drew blood, it doesn't seem bothered by the other fish though. The other clown seems to be spending a lot of time in a huge mass of Pulsing Xena and I've never seen either do that before.
Does this seem like breeding behaviour? I haven't changed anything diet or water wise so can't see why after 4 years I'm now getting attacked.
