They are similar to
Corydoras
pygmaes, another
dwarf Cory, but the black diamond shape in the caudal
peduncle and into the tail of hastatus, with
the top and bottom of this diamond ringed with white,
tells them apart as pygmaes sports a black
band that runs the full length of the body, ending
just short of the tail end, and ending in a slightly
broader band. 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: A very small mid-water shoaling
Cory in that it doesn't spend as much time on the
substrate as other Corydoras do, and seems
to prefer to sit on the leaves of aquarium plants
rather than sitting on the bottom. As mentioned you
should house these dwarf Cory's with each other in
a shoal with about about 1 dozen being a nice number
in a species tank, as these small Corydoras
will not do well in a community tank with robust tankmates
unless they are housed with small unagressive Characins.
Diet: Smaller foods for this Corydoras
such as crushed flake, tablets, grindal worm and washed
brine shrimp. Small frozen bloodworm is also a good
food. Remarks:
This is the smallest Cory to date and the females
usually are a bit bigger than the males.
