Typical rabbit needs a minimum tank size of 75 gallons, eats algae, particularly hair algae, also eats meaty foods, timid at first but will come out of hiding once comfortable, colormorphing body that changes with their mood or time of day, get to be 9+ inches one day, uh, will jump out if you scare them good enough, Other than that perfectly great fish for any tank. Will not mess with any fish or corals i know of. Look for a blue line rabbitfish. Very cool blue,teal,and green, and olive yellow with glowing bluish eyes.
