Guapore Corydoras (Corydoras Guapore)

Guapore Corydoras are incredibly docile, very peaceful and are a super easy fish to own. These Corys are an excellent Catfish choice for the established softwater community aquarium. However, these fish will do better if kept in groups of 4 to 6 individuals due to their shoaling nature.

It would be better if you housed Guapore Corys with small to medium tankmates such as Rasboras, Tetras and Danios and avoid much larger, more aggressive or boisterous fish, or they will get easily stressed. These fish thrive in quieter aquariums, where you will see them swimming together in groups, generally with their heads in a slightly elevated position.

Your aquarium needs to be well planted with several hiding places, and the substrate needs to be relatively soft; therefore, sand or smooth gravel would be a good choice. Filtration is an individual choice with either external or internal power filters with a good water flow. You should perform frequent partial water changes as this species can be susceptible to high nitrate levels. Corydoras can breathe air intestinally, so you should leave a small gap between the surface of the water and the lid so the fish may come up to the surface and take in air.

Guapore Corys have a short compact head and large eyes. Their bodies are sandy coloured that can change to an orangey-yellow when in good condition. They also display reddish blush cheeks, have very subtle spots and present a blueish black blotch on the caudal peduncle. They also have an adipose fin with a black blotch to rear, their dorsal fin has spotted bands, and their Caudal fin has a prominent banding of 8 to 10 rows of spots.

Natural Habitat

Guapore Corys are endemic to the Guapore River Basin within the upper Rio Madeira basin in northeastern Bolivia and western Brazil in South America. They inhabit inland waters that are warm, clear and acidic, typically stained brown from tannins and other decaying matter.

What to feed the Guapore Corydoras

Guapore Corys are most active at night, so feeding them once before lights out is usually enough. However, you can easily persuade these fish to eat during the day. Guapore Corys are somewhat adapted to forage on zooplankton; this means you will need to feed them on a diet containing plenty of live food such as artemia, daphnia and suchlike. You will need to supplement this with dried food such as sinking pellets or wafers alongside frozen fare such as brine shrimp or mosquito larvae.

How to sex the Guapore Corydoras

It is somewhat straightforward to differentiate between male and female Guapore Corydoras. Females will usually grow a little larger, are deeper bodied and are noticeably broader than males. In contrast, males have spiked dorsal and pelvic fins, whereas females are rounded.

How to breed the Guapore Corydoras

Guapore Corys are rarely bred in home aquariums; however, the method is usually similar to many other Corydoras species when successful.

It would be better if you have a ratio of two males to every female. When the females are noticeably full of eggs, you should perform a significant water change with cooler water and then increase the oxygenation and the water flow in the tank. You should repeat this daily until your fish spawn.

These Corys may deposit eggs among fine-leaved plants, on the aquarium glass, or in spawning mops. Spawning mops are highly recommended as they help the easy removal of eggs.

Once spawning has finished, you should then remove either the adults or the eggs; you can usually gently roll the eggs up the glass with your finger. You should then place the eggs in a separate container making sure the water is the same as what's in the spawning tank and that it is well oxygenated.

Various breeders add a few drops of methylene blue or an alder cone or two into the container to prevent the eggs from developing a fungus.

Incubation usually takes around 3 to 4 days, and once the fry has fully absorbed their yolk sacs, you can then give them small live foods such as baby brine shrimp and microworms.

Guapore Cory fry is not the easiest to raise, as they require excellent water quality; however, they seem less susceptible to diseases when maintained over a thin layer of sand rather than a bare bottom.
