Which Creatures?

Which Creatures are suitable for the Nano Marinus Cube?

A small Nano Cube should only be home to creatures for which such an aquarium offers a viable long-term habitat. A small coral requires little space, for example - and the same goes for a living sponge, a colony of mushroom polyps or tube worms. Other suitable creatures include 2.5 cm long gobies, which have a reduced air bladder and are not very active swimmers, tiny shrimps and other crustaceans, small snails or echinoderms such as serpent stars or starfish.
