It all depends on the individual shrimps' personality. I was skeptical about getting one, because I already have two skunk cleaners. I did anyway. He is big, I mean real big, and was scared he might cause damage. But I keep him well fed and there is plenty of rockwork for things to hide. He often hangs out in the back and always wants to be left alone. He might chase my cleaners when they get in his way or bother him. Ive had him for awhile with no problems.
