32 gallon biocube stocking

I currently have a firefish, 2 clowns, watchman goby, pistol shrimp, several hermit crabs and snails. I had bought a green chromis but it died in transport. What else, if anything could I add without crowding the tank? I would like something more on the active side if possible. Someone said the chromis may not be a good idea for a smaller tank like this due to aggression. I like the lawnmower blenny, but I don't know how well he would fit in with my current tank stock. There is definitely plenty of algae for it to eat.

You could , but lawn mower blenny’s will take over your rock work. Not so much in the water way .

I read that they hop around from rock to rock grazing, I think that would be a nice little addition. My firefish is actually very active, I was worried it would be really shy, but it has been out most of the day hovering around his hiding hole. Would a chromis be too aggressive for a tank this size? I also was interested in a royal gramma, but I know they also act similar to fire fish, and read there may be an issue with aggression between those two.
