A must have species if you are a keen Corydoras keeper. Females grow larger than the males. Lineage: Placed in Lineage 4 which includes two of the dwarf species and a revison would be a resurrection of the disused Microcorydoras (Myers, 1953) with the designated type species: C. hastatus. Aquarium Care: Will do best in a small species only tank or kept with small tankmates such as small tetras and dwarf rasboras. C.pygmaeus is a bit like C. hastatus in that it likes to shoal in midwater and as such should be kept in a group of at least six. Substrate can be of fine sand and plants such as java moss and java fern can be used alongside rockwork for further effect. If kept in a species tank for breeding, a fine substrate, java moss and a sponge filter would suffice with weekly 50% water changes to keep the water pure. Diet: Small foods such as microworm, grindal worm, good quality flake and tablets. Frozen foods such as small bloodworm.
