Yes it can. At night, they throw out sweeper tentacles that can kill other corals

Be careful with that green Zooanthus. Often call Zoo for short. They can be very toxic and can get you sick.
please do a little research on coral toxin.
it seem that you are new and purchase a 2nd hand system. Good luck and have a lot of fun.
