Help me take a long look at my 10g stocking!

[Unodostrace]

I have a 10g reef that’s been up and stable for about a year strong. I currently have a yellow clown goby, and a pistol shrimp goby combo and a small CUC. I would really like to add one more fish to get a little more action on the rocks/water column but don’t want to stress the stocking too much.

Is there any fish or critter I could add to get a little more out of my 10g or do I just need to stay where I’m at?

I’m not a newbie when it comes to aquariums, so I can handle a little overstocking with consistent husbandry. Don’t mind the algae, the picture is pre-scrub/water change. Thanks!

A Pygmy wrasse might be just what you’re looking for.

Could also get a baby clown fish
