Slant Bar Corydoras (Corydoras loxozonus)

The Slant Bar Corydoras is an excellent choice of Catfish for an established community aquarium. These Corys are good-looking fish that are relatively easy to keep and are suitable for the beginner aquarist.

The Slant Bar Corydoras is a peaceful shoaling fish best kept in groups of at least six individuals. Keeping these Corys in more significant numbers will result in a much more natural-looking aquarium and makes for an interesting display.

You can house Slant Bar Corydoras with most fish available in the hobby, including Dwarf Cichlids, Tetras, small to medium-sized Barbs, Gouramis and other peaceful Catfish. These Corys may prey on some more petite Dwarf Shrimp but are safe with larger shrimp and other ornamental invertebrates. However, it would be best if you refrained from keeping these fish with larger, more aggressive fish as they will feel intimidated and get outcompeted for food.

In order to protect the delicate barbel area, these corys should be kept on soft sand substrates. In addition, this somewhat shy species will also feel more secure with plenty of bogwood and shady planted areas.

As these Catfish are very sensitive to elevated nitrate levels, frequent partial water changes are necessary. In addition, this species does not fare well at high temperatures.

Slant Bar Corydoras have a greyish-tan body with small black spots and a very variable pattern. For example, some individuals display a solid dark slanted line along their body, and others show a broken one. In addition, these Corys display a black band that extends over the eye from the top of their head to the base of their caudal fin.

In the home aquarium, the Slant Bar Corydoras will readily accept most good quality dried foods such as granules, flakes and sinking pellets. These modern food products have been developed to provide all adequate nutrition to maintain your fish's health and dietary requirements.

Providing additional foodstuffs such as live, frozen, and freeze-dried meals such as bloodworm, daphnia, and tubifex once or twice a week will provide additional benefits to your fish's health and well-being but is not a must for this fish.

It should be noted that bloodworms should only be given as an occasional treat and should not be used as the staple diet as they are difficult for fish to digest and can potentially cause blockages.

This fish is an omnivore in the wild, meaning it will consume some vegetable matter. Although most modern fish foods take this into account and include them in their products, you can still supplement your fish's diet with blanched vegetables such as spinach, broccoli, and zucchini. Ensure you do not overfeed your fish and remove any leftovers the following day.

Sexual Dimorphism

The difference between the male and female Slant Bar Corydoras is usually quite evident when adequately conditioned. From above, females will appear wider since their underbelly is larger. The length of males is also shorter than that of females.
