Space Invader help

[Hibiscus Tree]

I bought this space invader a month ago. It’s about 2x2 inch with 7 eyes total. But I only see 1 sweeper at night. Is it normal to have just 1 sweeper? Anything I should do to help if it’s not normal?

Yeah that's pretty normal, all my corals that send out sweepers usually only put out one or two, all of them if they sense another coral nearby (irritated)

It won't stop at one though the name space invader is spot on for its behavior, soon you're going to be begging for some one to buy that mop of death from you.

Mine does the same thing from time to time, sometimes all of them at once and sometimes just a few.
Be careful what those sweepers touch becuse they will irritate or kill whatever they touch, I had to relocate mine recently so it won't stress anything out.

Thx for the help. I put my at the back corner with nothing else around it. The only problem is my BTA moving every night, I can’t get it to stay in one spot. Hope it won’t kill any of my corals.
