60 × 30 × 30 cm · 54 l
Three levels of the tank occupied by three small species, none of which grows into a problem. This is the shape a 54 litre tank is best at, and it stays interesting for years.

This is the overlap of every species in it — the narrower it is, the less room you have to drift. Check it against your tap before you buy anything: tap water tool
The stocking
Why it works
Celestial pearl danios hold the middle, pygmy corys work the bottom in a real group rather than the sad trio shops sell, and the amanos clean up after both. Six amanos, not five — our own engine flags a smaller group, and a published stocking that trips our own check would not be worth reading. The danios display best with more females than males; two females per male keeps the sparring ornamental instead of exhausting.
