Ooooh! Those two sound nice, I definitely won't touch the red stuff yet then!

I tried to nuke them before using Joe's Juice and a syringe, but I think it released all that gunk that caused tons more of them. Thought I could just start living with them. Hahaha - they hitched in on the live rock I bought - was not cooked or cured. As for copperband fish or even file fish (which I don't think look too pleasing,) are they reef save, and not aggresive?
