I think both are semi aggressive but I’d think add the dotty back first. I know mine likes his place in the scape and my clowns could care less about the scape. So I’d assume let the dotty back get his spot first before adding the clown.
How many gallons is yours? I've heard mean things about dottybacks
“Heard mean things about dottybacks” bahahaha
Mine is in a 75 gallon. You should consider a pistol shrimp goby pair instead of the dotty back. I also have a 20 and wouldn’t consider a dottyback in it. I have a clownfish, goby pistol pair, fire fish, and tail spot blenny
For size problems or for just overall aggression? I'm willing to just not get a clown if that's the case
They're both territorial so I'd get the one that you want most, you could also get some smaller fish as well like a YWG and tiger pistol shrimp, clown goby, or yasha goby and pistol shrimp pair. Something that's more of a bottom dweller would fit in that tank with a clown or dottyback no problem since both of those are mid to top tank fish.
Mine took a couple days to get used to his new home.
To start eating or to start swimming around?
To start swimming around, it ate almost immediately but I feed the same food my lfs does so it’s a little easier transition for the fish.
