Corydoras hastatus is a very small “mid-water shoaling” Cory that doesn't
spend as much time on the substrate as other Cory's do, and seems
to prefer to sit on the leaves of aquarium plants rather than sitting
on the bottom.
House these dwarf Cory's with each other
in a shoal of about 10 being a nice number in a species
tank. These small Corydoras will not do well in a community
tank with large, robust tankmates> They would prefer to be housed with small unagressive
Characins.
This is one of the smallest Cory to date and the
females usually are a bit bigger than the males. 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, sets
them apart. 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. The specific epithet hastatus means with a spear, in reference to the spearhead-like spot on the tail root.
Akin to most of this genus, this is a very peaceful fish,
and is best housed with small to medium tankmates such as
Tetras, Rasboras and Danios or in a
species tank due to their small size.
Bred as early as 1988, set-up in a 16” x 8” x 8”
tank furnished with a thin layer of sand, Java Moss and a sponge
filter. They spawned after a cool water
change, laying their eggs on the glass sides and in the Java Moss.
They also laid eggs on a small piece of bogwood in
the tank.
Eggs were removed to a small container, they hatched 6
days later and started on Liquifry for egglayers for
3 days, then on to brine shrimp.
Small pieces of food are needed for this Cory
such as brine shrimp, crushed flake food, tablets, freeze dried blocks
of tubifex stuck on the sides of the tank and any such food that
will fit in to their tiny mouth's.
Although the fish is generally a mid-water dweller, a fine gravel or sand substrate should be provided since it will occasionally burrow.
