thanks, you two.  I'll try and get some more pix soon, especially of the 125 as they're all blurry and full-tank.   I'm so surprised by the polli.  I got it at 8" and it's 12" already...almost as large as my lower jaws and the rest of the smaller uppers aren't growing much at all.  I do feed the little ones more than the larger-growing ones.  I'm anxious to see how large it's going to get as the max reported size that I can find is only like 14".
