Corydoras agassizii

Known to be found in Brazil and Peru waters. There are many corydoras of similar patterns to easily mis-identify and there are also a number pattern varieties within the sub-species. As for C. agassizii, this species was identified in 1877.

Planted or Sand floor works well for the species. Primary as a collector species for me to say i have it !

As most corydoras, they are fond of blood worm, daphnia, micro worms and once they are use to it, will need some encouragement on sinking dry sucker food or tablets.

For Microworms, make sure to wash them clean and search for foreign parasites before feeding as they can bring in unwelcome "alien" visitors into the tank. Microworms are good for breeding and typically you would want the tank to be empty of plants and gravels for ease of cleaning.

Often in mixed species tank, one common complain is that corydoras can't get the food in time since they are not mid-swimmers nor use their eyesights to do it. If there are other fish species who seek for food in mid-stream or floating on water surface aggressively, there maybe need to ensure sufficient leftover foods are available to the bottom dewellers as by nature they are scavanger in the wild and rather timid to compete effectively. In the wild, often dead insects are found in corydoras stomach however in confined aquarium setting, there may not be much food to be found in the debris.

One possible alternative is to off the lights so that the bottom dewllers have a chance to fill their stomach or throw the food at different locations hoping to buy sufficient time for the food to sink to the bottom before getting the attention of other fishes.

In a all corydoras tank, we do not have this issue.
