Brochis Multiradiatus - Wild Caught 8cm

Brochis Multiradiatus

For a fish that looks nearly identical to a corydora, the Brochis multiradiatus or hog-nosed catfish is actually in a different family. These fish however share essentially all of the same behavioural traits as something like a bronze corydoras. What's great though and one of the main differences is just how big these catfish get reaching a size of 12 cm which makes them perfect for systems with larger fish.

Brochis has a beautiful emerald green colour from head to tail with an equally stunning gold belly. They have a shimmering metallic sheen which captures the aquarium light amazingly well which makes these fish very noticeable in the aquarium. Their larger size makes them a species to add with semi-aggressive tank mates as they are usually left alone. Their active bottom-dwelling behaviour also makes this species a great dither fish option with shy tank mates.

Just like other corydoras species the Brochis catfish 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. The larger size of the brochis catfish makes them particularly effective at this behaviour which makes them a great alternative to the more basic corydoras options. Brochis catfish are not shy fish either like plecos and are constantly active, making them a great and popular fish for community and planted aquariums. These fish are also considered to be schooling catfish, in the wild they are often seen in large groups however in the home aquarium it is recommended to keep at least 3 or more. An ideal school would be around 6 plus individuals to really make them feel comfortable and to add some activity to the tank.

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 group of 3-4 catfish and let a pair naturally form. Given the price of these fish, it is a task that is easier said than done however the more these fish are bred, the better the chances of the price decreasing on them. Females are often triggered to spawn after being fed high-quality food and a slight reduction in the temperature through a cold water change.

Tank Recommendations for your Brochis Multiradiatus

As Brochis catfish reach around 12 cm as adults it is best to keep them in an aquarium with a minimum volume of around 70 litres. A larger aquarium will always be better due to their active behaviour and it also allows for the space to keep other tank mates. A sand substrate is best as coarser substrates like gravel often result in catfish damaging their barbels. Brochis multiradiatus catfish will love large, open sand beds however plants and hardscape can certainly be included with no issues. This will give the catfish places of refuge and make them feel more comfortable.

Suitable Tank Buddies

Brochis multiradiatus Catfish are an incredibly peaceful fish which can be kept with an absolutely massive range of community aquarium. They do not display any aggression even when breeding and make for a perfect addition even with sensitive or shy fish. The only factor that should be considered is that these catfish are almost exclusively a bottom dwelling species which means that any super active or large top dwelling fish may outcompete the corydoras for food.

Usually Compatible

community fish such as rams, tetras, angelfish, discus, rainbow fish, and many more.

Sometimes Compatible

Blue Acara, Severum cichlids, along with other large and semi-aggressive cichlids may pester the catfish.

Rarely Compatible

Large-mouthed and aggressive species such as Oscars or jaguar cichlids may prey on the catfish. This is especially important as Brochis multiradiatus catfish have spines on their pectoral fins which can get lodged in the predators throat. This can result in both the corydoras and the predator fish's death.

Feeding your Brochis Multiradiatus

Just like any other bottom-dwelling catfish these emerald catfish should be fed a range of sinking pellets and frozen foods. The ideal diet would be a good quality micro slow sinking pellet or crushed flake, supplemented with frozen bloodworms, black worms, or even live foods like baby brine shrimp or micro worms.
