They thrive in schools. Therefore, you can add more of the splendens as you like if you want to have such great emerald coloration in your aquascape. The group schooling behavior of the fish is also the most interesting thing you’ll ever see in your community tank.

Moreover, they are sociable and friendly with other fish from different species. They don’t mind sharing their space with the other fish as long as the tank mates are not aggressive.



Brochis Caring and Tank Guide


As mentioned, the life expectancy of the brochis is up to ten years or more. However, you can achieve this only if you make a good approach to the tank habitat.

It is best to mimic the natural habitat of the fish so that they can thrive for a long time in the future.

The emerald catfish are basically hardy. So, they can survive in any condition of the water and tank.

However, you need to see the parameters and monitor them to maintain good conditions for the fish to live.


Here are the recommended tank parameters to check:


  • Temperature: 68°-82.4° F (20°-28° C)
  • pH: 5.0-8.0..
  • KH: 2- 15 dKH
  • Minimum tank size: 55 gallons



The minimum tank size above is ideal for a school of six adults. If you add more fish, keep in mind to add 10 gallons for every single fish you add to the tank.

If possible, you will want to maintain softer water to make your fish live longer, although they can survive in any condition of the water.


During the day, your emerald splendens tend to look for shade and hiding places to enjoy their napping and resting time.

To accommodate your pets doing these activities, you could add some rocks and driftwood there.

If you purchase new driftwood, make sure you boil it first to remove the toxins from the wood. When it gets colder, you could then add them to the tank. Caves are also a great idea.


Your brochis buddies are natural scavengers. So, you will mostly see them exploring the bottom part of your aquarium.


Do not add coarse substrate since it will hurt their bodies. Instead, you could use softer sand and gravel.

This won’t hurt their underbelly. The fish are adaptable in tropical conditions to cooler water. But you must also monitor your fish conditions to prevent something bad from happening.


Brochis Tank Mates


It is a peaceful fish that you can pair with any other animal in your small aquarium. But if you are creating a community tank with a lot of species, consider preparing a larger aquascape to accommodate all of the fish.


You can pair them with dwarf cichlids and angelfish.


If you are adding invertebrates, you would want to measure them first. The smaller invertebrates can be the prey for your brochis.


Brochis fish are basically passive, making them prone to being targets for larger fish. So, make sure you only have peaceful fish in your community tank. Don’t put any semi-aggressive fish in the tank since they will ruin the peaceful home for your companions.



The beginning of other species in the community tank can be indifferent. However, some larger fish might be able to bully your catfish or vice versa. Add more hiding spots to give them space and time to withdraw and adapt to the environment.

If you add rocks, you don’t need to be surprised when your catfish goes missing for a few days. They enjoy their “me-time” underneath the rocks.


How to feed Brochis


The bottom dwellers will accept any food you give them. Good foods must be available to maintain wellness and fitness.


They are natural scavengers. So, you can give them sinking pellets and bloodworms in which they can retrieve them from the bottom of the tanks.


They love to fetch food from the bottom of the tank, substrates, caves, and holes.


You could give them flakes and sinking pellets occasionally and they will be happy with them.

Sinking pellets are the ideal routine food for them because they won’t have to compete with the top and middle dwellers who tend to get their food from their own territories. Otherwise, they will not get the food that they need.


There are sinking pellets that are purposely manufactured for this species. It is much better if you can focus on foods that are made for them.


Your splendens cory fish are also fond of seaweed sheets for their diets. You could also give them nori. Make sure to choose unsalted nori to feed your brochis.


Bloodworms are also their favorite. Make sure you wash your hands after giving them the bloodworms since they can cause allergic reactions to your skin.



Brochis Breeding guidelines



It is difficult to breed emerald catfish. Although it is easy to care for them, breeding your brochis buddies can be difficult to do. Lowering the temperature of the water will trigger them to spawn.


Lighting should be dimmer with the help of the floating plants.


Add a spawning mop to provide the adults a place to spawn. Females will lay up to 300 eggs. Those will be spread around the plants and tank glass. It is recommended to have a breeding tank. When the fry turns larger, you can put them back in the main tank.
