20 Gallon FOWLR

Hello all! I am a past reef keeper that's (sorta) getting back into things. I have an office that I'm looking to put my recently bought 20 gallon tank in. Where I live unfortunately does not allow corals or inverts really, so it will have only fish (currently a two gobies and a chromis, will add a ocellaris clown and perhaps another) along with live rock. A few question I had were...

Since I can't really have a normal CUC, any other fish recommendations?
I figure lawnmower blenny, and that's all I think think of, I would like to keep it as low maintenance as I can

What should I have for filtration?
I used to have a LPS tank and know bio balls and HOB filters were not so great because of nitrates, but should I keep the HOB my current tank came with since only fish?

Any help appreciated!

I would not put a lawnmower in such a small tank unless you plan to feed it algae all the time..

I also wouldn't do anything but water changes of about 5G ever month or so if that in a FO tank of that size..

Just live rock/sand and a powerhead.. Thats it..

Being blunt and having fun
Straight up INTJ
