Corydoras nattereri
Neomeris
Neomeris annulata
Tiny, elegant calcified algae with a barrel-shaped body ringed with white calcium bands at the tip. Short-lived (weeks to months) but reproduces readily in stable reef tanks. An interesting hitchhiker and occasional deliberate addition. Fish tend to leave it alone due to calcification.
