Honestly, though, I think the BGA is worse for shrimp than the Maracyn. In the BGA plague of '03 on my 75 gallon tank, I lost all of my amanos. In retrospect, I'm sure it was because the BGA smothered out all of the "normal" algae and since there were only a couple of fish in the tank at the time, I was feeding VERY sparingly to try to keep the nutrients down (which, by the way didn't work). The poor little buggers must've starved.
It is sad because up to that point they had seemed virtually indestructable.

My water quality is good, and has been for a long time. One website I read said to isolate if it is velvet by shining a flashlight on my fish in a dark room. My fish lit up like gold dust. 
I've never treated for velvet, but now I'm afraid I must. I also have weird algae that looks brown... is that it? My 2 shrimp seem unaffected (I guess because of their exoskeleton). How do I treat my tank, without hurting my shrimp?
