I have a 90 gallon, and currently have a dragon goby. I love gobies and blennies, but I know I have to be careful about mixing. Here's what I'd like, long term. I know I have to add them slowly. Is there any particular order I should add them in, or any that I should skip altogether?

Diamond goby
Starry blenny
Yellow Watchman Goby
Green Clown Goby
Purple firefish
Scooter Blenny
