I introduced new Corydoras. This time the Corydoras melini, 6 of them. According to Planet Catfish, they grow to max 4.5cm, and this was one of the reasons I chose them for this Cory aquarium.
I am feeding them with Aquatic Nature Hi-quality Krill flakes, sinking wafers from Sera, and Hikari Protogen (infusoria sticks).
