Unique Fish for a 40 Breeder

[Adamantium]

Hey guys,

I’m trying to find one or two last fish to round out my 40 breeder’s stocking.

I’m debating a blue spotted jawfish, but am worried about it destabilizing my rocks. I also only have a top that covers ~90% of my tank, and I’m sure it would find that 10%.

Any other ideas for a cool fish, or two, that would do well in a 40 breeder? Apologies if this isn’t the place to ask this. Just trying to find some opinions about fish that are less common/more unique.

Thanks!

Oh, right. Current stocking is:

2 clownfish
1 indigo dottyback
1 Randall’s goby
1 candy striped pistol shrimp
2 neon blue gobys

Nutrient levels are very low thanks to a large skimmer.
