How Many Cory Catfish in a 55 Gallon Tank?

A 55-gallon tank can comfortably house up to 6 Cory Catfish, depending on their size. When getting more than one cory, it is best to get a group of at least 3 so that they have companionship and don’t feel isolated. It is important to remember that Cory Catfish are very active fish and need plenty of room in the aquarium as well as places for hiding during the day or night.

The ideal water temperature for these bottom feeders should range between 75-80 degrees Fahrenheit with a pH level around 7.0 and weekly partial water changes of 25%.

Cory Catfish are a popular species of fish to keep in aquariums due to their peaceful nature and small size. They can be kept in groups as long as there is plenty of space, so when it comes to stocking a 55 gallon tank with Cory Catfish, you could easily fit anywhere from 10-25 depending on the size of your fish. It’s important that each Cory has enough room to swim around and hide, so if you’re adding more than 10 it’s best not to overcrowd the tank.

How Many Catfish Can I Put in a 55 Gallon Tank?

When it comes to stocking your 55 gallon tank with catfish, there are a few things to consider. First and foremost, what type of catfish do you plan on keeping? Different species of catfish have different needs in terms of water quality and space requirements.

Once you’ve determined the type or types of catfish suitable for your aquarium, the next step is to determine how many fish can comfortably fit into your tank. Generally speaking, depending on the size and temperament of the selected species, a 55 gallon tank should be able to accommodate between 10-20 adult sized specimens as long as good filtration is provided and regular partial water changes are done (at least 25% every week). It’s important not to overcrowd either; too many fish can lead to increased ammonia levels which will cause harm or even death for the fish.

An alternative approach would be using smaller schooling species such as Corydoras or Tetras if you’re looking for more activity in the tank without having too much stress on its inhabitants. Whichever option you choose, research beforehand about each specie’s social behavior so that they can live peacefully together – some fishes may get aggressive towards each other when territorial boundaries are violated!

How Many Cory Catfish Should Be Kept Together?

When it comes to keeping Cory Catfish together, the general rule of thumb is to keep at least four or more fish in a tank. This is because Cory Catfish are a very social species and will feel more secure when kept with other fish. Keeping multiple Cory Catfish also helps to reduce aggression between individual specimens, as well as adding interest and activity levels in the aquarium.

It’s important that you provide enough swimming space for each cory by dividing the tank into several different sections, or use decorations such as plants and rocks to create hiding spots. You should also be aware of their relatively small size; while they may seem tiny on their own, many individuals can reach up to 4 inches long when fully grown! Lastly, make sure your water quality is top-notch.

As with any fish species, poor water conditions can lead to health issues down the line if left unchecked – so regular testing should always be done before adding new fish into your aquarium community!

Can You Keep 4 Cory Catfish Together?

Yes, you can keep four cory catfish together in an aquarium. Cory catfish are social fish that prefer to be kept in groups of four or more. When keeping them in large groups, it is important to provide plenty of swimming space and hiding places for the fish so they feel safe and secure.

You should also make sure that all the corys get enough food without one dominating over another. An ideal tank size for a group of 4 corys would be at least 30 gallons with plenty of smooth rocks, driftwood, and plants as well as a substrate like sand which will help protect their delicate barbels (whiskers). Also, don’t forget to include regular water changes and check your water parameters regularly!

Keeping multiple cory catfish is an enjoyable experience once you understand how they interact with each other; watching their playful antics brings joy to any aquarist’s heart!

How Many Cory Catfish Can I Put in a 5.5 Gallon Tank?

A 5.5 gallon tank is the ideal size for a small group of Cory Catfish, or Corydoras. A single adult catfish should have at least 1-2 gallons of water to itself. Therefore, you can comfortably house two or three corys in a 5.5 gallon tank; any more than that could lead to overcrowding and poor water quality issues.

When selecting your corys, make sure they are all the same species as some grow larger than others and need extra space in the aquarium environment. Moreover, ensure that you provide plenty of hiding places such as driftwood, rocks and artificial caves so each fish has its own territory within the tank to explore and feel secure in their home environment. Lastly, since these fish are bottom dwellers it’s important to have a gentle filter system with low flow rates so they don’t get pushed around by strong currents while scavenging for food on the substrate!

7 Tips for Keeping Corydoras in an Aquarium

How Many Cory Catfish in a 29 Gallon Tank

A 29 gallon tank is an ideal size for a Cory Catfish, as it allows them to swim comfortably and explore their environment.

However, when considering the size and activity level of this species it may be best to keep closer to 30-35 as overstocking could lead to poor water quality and an increased risk for disease.

How Many Cory Catfish in a 10 Gallon Tank

When it comes to stocking a 10 gallon tank with Cory Catfish, the general rule of thumb is to keep no more than 4-5 individuals in this sized aquarium. It is important to note that while they are small fish, they still produce waste and require plenty of swimming room so overcrowding should be avoided.

How Many Cory Catfish in a 30 Gallon Tank

In general, it is recommended to keep no more than 3 Cory Catfish in a 30 gallon tank.

How Many Corydoras in a 60 Litre Tank

In general, it is recommended to keep a maximum of 5 Corydoras in a 60 litre tank. This allows each fish enough space to swim and reduces the risk of overcrowding, which can lead to stress and health issues for the fish. It’s also important to remember that when stocking a tank with any type of fish, you should ensure there is adequate filtration and aeration as well as plenty of hiding places for them.


In conclusion, the number of Cory Catfish in a 55 Gallon Tank is dependent on several factors. The size and type of fish, tank size and water chemistry should all be taken into account when attempting to determine how many Cory Catfish can safely reside in this tank.
