Stocking for waterbox 20g cube

[HonorableWhat]

So, i got a 20g waterbox aio for cheap that i plan to turn into a rock flower nem tank.

And im wanting to stock it with something uncommon.

Im fine with it being a single species only tank

Do you have a color preference?

 

[i cant think]

The smaller pipefish (These need a lot of pods to thrive),
Pink streaked/Possum wrasses,
Clown gobies (If you get a black or brown clown goby then you have an uncommon colour)

Nope. Im open to anything

Do you have a color preference?
