A small group of Abramites hypselonotus (marbled headstanders) , a bushynose pleco, and a small school of neons (cardinals are a bit high maintenance).
I've seen groups in much larger tanks, they are hardly inactive. I've also seen a single one in a much larger tank than the group (3K tank with bass, Asian aro, rays, giant gourami), and it did not stay in one place. It swam around slowly, but still moved around the circular aquarium.True but they are very inactive, plus the 56 has extra width as opposed to height, giving it extra swimming room.
Mine is in a 60, he spends 95% of the time sitting in one spot, going on a patrol every once in a while. Most I’ve kept or seen tend to have a similar behavior once they pass 6 inches.

Dwarf puffer colony with like 25-30 would be amazing!Id love to have a tank with some rare knife fish, so many to choose from! Or maybe a school of elephant noses?? School oof small puffers would also be cool...
