Corydoras Similis 4cm

Corydoras Similis

The Similis Corydoras is one of the most adorable little cory species in the aquarium hobby. These are great corydoras species for aquarists trying to branch out their collection after keeping more basic species like bronze or peppered cories. Corydoras similis are fantastic because they are small, have a light and contrasting colour along with offering all the loved corydoras behaviours. Similis Corydoras mostly have a black and silver colour with gold accents which is part of the reason they are so appealing. The stark contrast between the light and dark colours really makes these fish stand out in the aquarium whereas most Corydoras species tend to just be dark.

The body colour of the Julii corydora is generally a silver to grey shade which is overlaid with a scribbled patterning of jet black. The front half has a series of leopard-like spots that lead into the stripes that run along the back half of the fish, this is all starkly contrasted by the gold hues in the fins, belly, and cheek area. Just like any other corydoras species, the similis cories will constantly stir the substrate layer in order to look for food. This behaviour ensures they are keeping the substrate turned over and any debris in the water column, which can then be picked up by the aquarium filter.

They are almost exclusively bottom-dwelling fish and are an awesome option to add some life to the bottom of the tank. The similis cories are also considered to be a schooling catfish and it would be best to keep them in a group of at least 5-6 although more than this will never hurt. Differentiating males and females is possible where the males are often smaller and narrower compared to the larger-bodied females. The best method to identify is to get a school and let a pair naturally form. Females are often triggered to spawn after being fed high-quality food and a slight reduction in the temperature. The wild origin of the similis corydora is South America.

Tank Recommendations for you Corydoras Similis
As similis cories reach around 4.5 cm as adults it is best to keep them in an aquarium with a minimum size of around 70 litres. A larger aquarium will always be better since a larger school can be kept along with the space for other tank mates. A sand substrate is best as coarser substrates like gravel often result in corydoras damaging their barbels. They will also love plants in the aquarium and places for cover through the addition of driftwood. As these are tropical fish, it is best to maintain the temperature at around 24-26 degrees.

Suitable Tank Buddies
Similis Corydora is an incredibly peaceful fish that can be kept in an absolutely massive range of community aquariums. They do not display any aggression even when breeding and make for a perfect addition even with sensitive or shy fish. The obvious consideration would be to just avoid keeping anything that might harm this fish.

Usually Compatible
Angelfish, cardinal tetras, rams, discus, and similar peaceful South American species.

Sometimes Compatible
Mystus catfish, geophagus, veja cichlids, and other peaceful but potentially territorial species.

Rarely Compatible
Large and aggressive species such as Oscars which may prey on the Corydoras. This is especially important as Corydoras have spines on their pectoral fins like many catfish, this can result in both the corydoras and the predator fish’s death.

Feeding your Corydoras Similis
Just like any other corydoras these fish are very easy to feed. They will take a wide range of pellets, flakes, and frozen foods. Just like any fish though they should be fed a varied diet with a mix of different foods. The ideal diet would be a good quality micro slow-sinking pellet or crushed flake, supplemented with frozen bloodworms or even live foods like baby brine shrimp.
