How do you do a water change with little disruption?

I've got a black brittle and a grey serpent star in my 90 and they don't come out to play too often. They'll throw out a limb or two if some food gets tossed into the water column, but aside from that, they're pretty quiet.

 

I remember watching, however, a green brittle star attack and kill a pink skunk clown once. Not at all pretty. Trapped it against the tank wall and took care of it, quickly too. Also know of a green brittle star that ate a sailfin tang that was as big as your hand once too. He had a brief but very effective meeting with the business end of a tack hammer (this was NOT my doing!).

 

As far as those sand sifting stars go, they're all right, but nothing amazing. Unless you get tiny ones to start with, they're worthless in a nano. Not enough room to move.

my brother always bought stars, yeah u see them like once u put them in the tank. Then tehy are just like gone. But that was a 75 gallon tank, in a 10 you might see them more.
