Corydoras sp. CW049

Here is a short video showing my school of Corydoras sp. CW049 .  These catfish were imported from Peru, but they come from the region around Letecia, where Colombia, Peru and Brazil intersect.  They are similar to CW051, but the 49’s have proven to be easier to spawn.  This is one of my favorite cory cats, but they are pricey.  They swam around in the warehouse fish room for months and nobody bought them, so I decided to keep them for myself.  You will also see a larger cory in the video, which is CW117 from Brazil.  Also in the tank are a group of Apistogramma cacatuoides ‘triple red’, which are already spawning.  I thought that the cories would go into the caves at night and steal the eggs, but so far they have left the cichlids alone.

 

The aquarium is a 30-breeder aquarium that is top drilled in the back.  Water changes of about 15% are done 2x each week by topping the tank off with water and letting the excess drain out.  The filter is a Poret foam 5″ cube filter with a jet lifter that has an elbow and spout on the top.  That smooth 90-degree turn makes all the difference in the world when it comes to current in the tank.  I get the filters from www.swisstropicals.com .  The wood and caves provide structure and cover, but the catfish pretty much stay out in the open over the sand.

The tangled mass of plant-like matter in the back is Spanish moss, which you can get at most nurseries that sell supplies for planted hanging baskets.  I soak the moss in hot water, changing daily, for a few days to get rid of a lot of the tannin, but there is still plenty in there.  I do not mind the tannin, and the moss is a great place for the cories to deposit eggs (though it will be hard to see them in there).  The yarn mops are also for depositing eggs.  One mop is located directly in the current of the filter, and the other is on the calm side of the tank against the glass.  Hopefully I will see some signs of spawning soon.

The cories are fed at least twice each day.  Baby brine shrimp is given daily (along with all the other tanks in the room).  Other feedings may be flake (Brine Shrimp Direct deli, plankton and earthworm flake), sinking pellet (Sera plankton pellets), Repashy gel food (Bottom Scratcher or Spawn & Grow) or live black worm.  I generally feed each of those foods a few times each week, but not a lot of any of them.
