Different Goby and Blenny in a 33 gallon cube. Trouble or peace?

[Brazilian Reefer]

Hello there!
Will there be trouble having different Goby and Blenny in a 33 gallon cube? My reef tank size: 50x50x50cm - 125L (19.6x19.6x19.6" - 33g)
Really want Yellow Clown Goby, Randall Goby, Bicolor Blenny and Rock Algae. Must I choose only two of them?
Yellow Watchman was also on my list, but maybe he won't get along in the same space as Randall Goby (which is my favorite vs Watchman), am I right?
Thanks!

The gobies should be alright because they’re two separate genuses and gobies altogether - I have a Black Clown Goby and a Yasha Goby in a 75l 18” cube and they’re doing fine. The gobies tend to be more territorial so in that size tank I’d only have one.

Guess I'm going with a Bicolor Blenny and a Yellow Watchman.
Maybe adding a Rock Algae in the future...

I would go with only one blenny in a small tank, gobies can co-exist fine but I find blennies only co-exist if they’re added together, they’re a goby that can stand it’s own species/others or if it’s a large tank (3-4’).
