These are a
great looking little armored catfish that are rarely seen in the aquarium hobby
was able to get a group of some tank-raised fry handed to me from a top Germany
breeder while he was here for a visit.
The fish were barely a quarter of an inch when I got them, but as with
most Aspidoras species, they grew quickly.
Their grow out tank was a ten-gallon aquarium which was part of a larger
�fry system� that is all linked together with a total capacity of about four
hundred gallons which also runs thru an ultraviolet sterilizer.
I lost a few of the young as they were growing out, but of what survived,
within seven months the females reached a size of nearly one and a half inches
and males grew to just over an inch.
guessing at about six months of age, I placed the group into a fifteen-gallon
tank by themselves.
It looked as if I had a few females and about six males.
Males, not only are smaller is total body length, but are thinner bodied,
have more distinct black body markings and have a mostly black dorsal.
Females are full bodied; show more of a faint marble body pattern and
hardly have any color in their dorsal.
The tank was void of any substrate and painted black on the underside.
A single sponge filter with a good heavy airflow was used for filtering.
Water changes done every seven to ten days of approximately fifty
pH of 7.2, temperature at seventy-eight degrees Fahrenheit and a TDS reading of
256 were averaged.
A yarn mop was placed on the bottom of the tank for cover and spawning
was covered with a glass lid and light levels low.
I fed the fish usually twice a day, one feeding of a little live baby
brine shrimp and the second feeding of either live black worms, frozen
bloodworms or one of many flake or stick foods on hand.
month of being placed in this set-up, a few eggs were noticed in the mop and
stuck to the glass bottom under the mop.
The mop and eggs were pulled from the tank and placed in 2-gallon
container for hatching, in which a couple of drops of methylene blue and an
airstone with a gentle air flow was added.
In a few days the eggs hatched and I found four fry with their egg sacs
swimming along the bottom of the hatching container.
The following day I removed the fry and placed them in the �fry
system� (mentioned above) to grow out.
Microworms, along with some sponge filter squeezing were the first foods
baby brine shrimp was add to their diet a few days later.
Fry grow quickly, much quicker than most Corydoras fry!
