i am setting up a first saltwater tank. 120g 2x2x4. I would like to put a bulb tip in there because i think they are pretty cool. i like the orange or green. What is the care for these guys? Waterflow? Light? diet? I hear they move around alot? I was thinking of having live rock piled large off to one side of the tank, then have some sand bed open, then to the other side have a small pile of rock. probably 3 or 4 pieces. would it be a good idea to stick the bta on the small pile or will he navigate his way off of there. I figured if he only has 3 rocks to climb on then that limits his movement, but i didnt know if it will move in the sand or on the glass? any experience with these guys? also how big do they get and how do you trim them?:nerd:sorry for all of the questions. anxious newbie here.
