Adding one more fish....

[Arizonah13]

My current tank inhabitants include a pair of occ. clowns, a green clown goby & a cleaner shrimp. They've all been in the tank for over a year, so if I dare to consider adding one more, would my clowns blow a gasket on the new guy?

I've been thinking about adding either a tailspot blenny or a bicolor blenny which I imagine will be out of the clowns usual swimming space, but I do have my little green clown goby to consider- should I worry about him fighting with either of the blennies I mentioned?

(I have a 29g BC btw)

Thanks

I have a pair of clowns a watchmen goby,scooter blenny and a six line. In a 20gal tall. If you have a good skimmer IMO I would add one more.
