Beeker - I can tell you that IME the sweepers don't do any damage (surprised me, since I react violently to some stuff) but I did feel it when my froggy got mad during the move - I feel clumsy in gloves and took them off, dumb move. I have a friend who breaks out in horrible burns whenever he goes near a euphyllia (torch, frogspawn, hammer) and has to go to the doctor. Why he doesn't wear gloves is beyond me.
Lobo - glad you're enjoying the thread

Caulerpa needs trimming and careful watching; just today I removed much of what was on the rocks, it was turning clear and looked like it was getting ready to reproduce sexually which makes a horrid mess of a tank. There's a small green patch left, it'll be insanely huge before I know it.
ADD--> I forgot to mention, the flagfin is doing wonderfully. I questioned whether or not it would be smart to add another angel to the tank, but the halfblack is such a big eater he seems to have encouraged Midas. They compete constantly, and having someone threaten to take away his pellets or mysis spurs Midas on and makes him eat more. He's getting a little paunch on him now and the HLLE is starting to recede. He likes frozen, but I recently bought some Hikari 'Marine S' pellets and he goes absolutely crazy for those
I also recently added two Maxi-Jet 900 powerheads so there's about 20x turnover in the tank now. The fish actually seem happier, and the corals look great especially considering all the attention they get from Bulldog the halfblack, who loves to pick at them
