sorry, I am pregnant and spend a lot of time sleeping when at home so don't get to check this as often as I would like. I don't know how old they are but both are the same size at about 5" long. They are in a 180 gallon tank. I bought them from someone off reef central about 4 months ago or so where they were living in a 120 gallon tank before I got them so they are not strangers to each other. They have been fine until just recently, i have not changed the rock work around recently. Maybe the tang was just having a bad couple of days or soemthign because it doesn't seem to be bothering the trigger as much anymore, it is now letting the trigger back at if it swims at the top half the tank and the tng swims at the bottom half, so for now I guess they are okay with each other again. It still goes after it every once in awhile but then swims away quickly and isn't makign it stay behind the rocks like it was. I haven't been sticking my hands in the tank as much as I use to be just because I haven't been adding things lately or needing to rearrange things so maybe it just has other things besides me to worry about like some of you were saying so has decided to find something else to do but I think they are okay.
