Unless you have a large system like 500 plus gallons your most likely not going to be able to keep multiple cleaner wrasses. I had 2 in a 150 and the bigger one was so dom the other couldn’t come out of the rocks to even eat.
I think you’d have better luck with a Blue Streak Cleaner wrasse. I had one for more than 5 years. I don’t know anyone who has been able to keep a Hawaiian cleaner for more than a few months.
