Currently brainstorming stocking ideas for a 13.5 evo tank

[Not Otter]

I'm considering between a yellow striped cardinal, a percula clown, or a goby of some sort. The cardinal is the one I'm very interested in but I'm not seeing much in terms of keeping them. I would be interested in other cardinals that would comfortably fit though.

Yellow striped cardinal would be great for that sized tank.
