Yes for sure, ur aquarium needs to be set up IMO atleast 6 months, u need to have correct lighting also, they also are going to go where ever they want at first to find the perfect spot for themselves, they might stay there forever and then again one day it will move again. Might also note that sometimes they find powerheads and get schredded into a million pieces. But they are an awesome addition to aquariums. I have had many and when u see a clown swimming in one it is amazing. Good luck, hope u get u one.
