Hi, I have a 100 gallon tank that has been set up for about 4 months now. I have 2 clown fish and 2 azure damsels and I was going to add a yellow tang , two spot brittle tooth tang , lawnmower blenny , and a six line wrasse. Should I add a cleanup crew before I add these fish or is it ok to add at the same time.
thanks.
thanks.
