Incompatibility Between Cory Catfish and Cichlids

The incompatibility between cory catfish and cichlids is evident, as cichlids are known for their aggressive nature and intolerance towards other fish species, including cory catfish. Keeping these two species together can lead to potential problems in a community tank.

Cichlids, especially African cichlids, are highly territorial and will constantly bully and chase the cory catfish. This constant stress can lead to health issues for the cory catfish. Additionally, cichlids prefer hard water conditions, while cory catfish prefer soft water.

To create a peaceful community tank with cory catfish, it is best to choose tankmates that are peaceful and social. Good options include guppies, mollies, platies, shrimps, snails, zebra danios, neon tetras, rasboras, swordtails, and gouramis. These tankmates will live harmoniously with cory catfish and create a stress-free environment.

It is crucial to maintain clean water conditions, with zero ammonia and nitrite levels, nitrate below 20ppm, stable water temperature between 70-82 °F, pH level between 7 and 8, and water hardness between 5 and 19dGH to ensure the well-being of the cory catfish.

Reasons to Avoid Keeping Cory Catfish With Cichlids

Although cory catfish and cichlids may seem like potential tankmates, it is advised to avoid keeping them together due to several reasons.

First, cory catfish thrive in a species-only tank. By keeping them in such an environment, you can ensure their well-being and provide them with the best conditions for their specific needs.

On the other hand, cichlids, especially African cichlids, are known to be aggressive and territorial. Their behavior differs greatly from that of the peaceful and social cory catfish. Cichlids are prone to bullying and chasing other fish, including the cory catfish, which can lead to stress-related health issues.

Furthermore, cichlids prefer hard water, while cory catfish thrive in soft water. Therefore, it is best to explore other tankmates for cory catfish that will live peacefully alongside them, such as guppies, neon tetras, mollies, platies, and zebra danios.

Suitable Tankmates for Cory Catfish

Here are the advantages of keeping these tankmates together:

  1. Colorful display: Guppies, neon tetras, and swordtails add vibrant colors to the tank, creating a visually appealing environment.
